Abstract:

Abstrak: Bakteri pereduksi sulfat atau Sulfate-reducing bacteria (SRB) adalah jenis bakteri obligat anaerob kemolitrotof memanfaatkan donor electron H2. Kemampuan SRB mereduksi sulfat menjadi sulfida mampu mengendapkan logam toksik meliputi Cd, Cu, dan Zn sebagai logam sulfida. SRB memerlukan substrat organik seperti asam piruvat yang dihasilkan oleh aktivitas anaerob lainnya. Mekanisme SRB dalam melakukan reduksi sulfat, sulfat digunakan sebagai sumber energi sebagai akseptor elektron dan menggunakan sumber karbon (C) sebagai donor elekton dalam metabolisme dan bahan penyusun sel. Pada kondisi anaerob bahan organik akan berperan sebagai donor elektron. Pembentukan senyawa sulfida melalui proses reduksi yang ditandai oleh penambahan elektron dari bahan organik yang menyebabkan turunnya konsentrasi sulfat dan naiknya pH lingkungan. SRB pada kawah air panas nirwana ini hidup secara anaerob pada suhu lingkungan 600C - 1000C dengan pH 7,4 tingkat kekeruhan air cukup keruh dan kandungan air yang mengandung blerang dengan indikator bau seperti telur busuk dan lingkungan sekitar terdiri dari sedimen batu kapur. Abstract : Sulfate-reducing bacteria (BPS) is a type of chemolithotroph obligate anaerobic bacteria that utilize H2 electron donors. The ability of BPS to reduce sulfate to sulfide is able to precipitate toxic metals including Cd, Cu, and Zn as metal sulfides. BPS requires organic substrates such as pyruvic acid which is produced by other anaerobic activities. The BPS mechanism in reducing sulfate, sulfate is used as an energy source as an electron acceptor and uses a carbon source (C) as an electron donor in metabolism and cell building material. Under anaerobic conditions, organic matter will act as an electron donor. The formation of sulfide compounds through a reduction process is characterized by the addition of electrons from organic matter which causes a decrease in sulfate concentration and an increase in environmental pH. BPS in this nirvana hot spring crater lives anaerobically at an environmental temperature of 600C - 1000C with a pH of 7.4 the level of turbidity of the water is quite cloudy and the water content contains sulfur with an indicator of smell like rotten eggs and the surrounding environment consists of limestone sediments

Abstract:

The Dunka Road deposit is one of several Cu – Ni – platinum-group element (PGE) sulfide occurrences found along the northwestern margin of the Duluth Complex, where the host troctolitic rocks are in contact with metasedimentary rocks of the Animikie Group. Magma contamination through assimilation of sulfidic argillaceous country rocks is generally recognized as having played a key role in the genesis of the mineralization. Three main types of disseminated sulfide mineralization have been identified within the Dunka Road deposit: (i) norite-hosted sulfides, (ii) troctolite-hosted sulfides, and (iii) PGE-rich sulfide horizons. The norite-hosted sulfides are found either adjacent to country-rock xenoliths or near the basal contact. The troctolite-hosted sulfides form the bulk of the deposit, and occur throughout the lower 250 m of the intrusion. The PGE-rich sulfide horizons are typically localized directly beneath ultramafic layers. The composition of the different types of sulfide occurrences is modelled using Cu/Pd ratios. It is shown that each type results from the interplay of two main parameters, namely the degree of magma contamination and the silicate magma to sulfide melt ratio (R factor). The norite-hosted sulfides formed at low R factors and high degrees of contamination, as expressed by their PGE-depleted nature, low Se/S ratios, and elevated content in pyrrhotite and arsenide minerals. The troctolite-hosted sulfides formed at moderate R factors and small degrees of contamination, as shown by their moderate PGE content and mantle-like Se/S ratios. Finally, the PGE-rich sulfide horizons are modelled using elevated R factors from an uncontaminated parental magma, which is substantiated by their elevated noble metal content and Se/S ratios, and low pyrrhotite to precious metal sulfide ratio.

Abstract:

First the fretting wear behavior of CuS nanoparticles additives in grease were studied. The results show that the fretting wear volume reduce significantly when CuS nanoparticles additives add to grease. At the same time the existence of sulfid nanoparticles can reduce friction coefficient at the latter fretting time. The results of XPS tests show that Cu, Zn, Ni, S and B elements were founded in the film of wear scar. Secondly the effect of antiwear and oiliness additives on fretting wear behavior of nanoparticles additives in Grease were studied. It was found that when some antiwear, oiliness additives (such as T203, T322, stearyl alcohol or stearic acid) and sulfide nanoparticles were added to urea grease, a synergy effect between the two types of additives made fretting wear volume more small than that of either additive. Based on the results of contrast experiment and some analysis of fretting wear scars, we present the idea that two additives react with friction surface step by step. That is to say, the high chemical activity of CuS nanoparticles decompose first and form protective layer, the heat converted from chemical reaction of CuS decomposition and mechanical motion promote composition of common oil additives, thus protective layer is formed once again and wear volume further decrease.

Abstract:

Učinci Vulkanskih Erupcija Na Okoliš I ZdravljeVulkani predstavljaju prijetnju za gotovo pola milijarde ljudi: danas je na Zemlji aktivno oko 500 vulkana, a svake se godine događa 10 do 40 njihovih erupcija. Posljedice erupcija vulkana odražavaju se na okoliš, utječu na klimu te na život i zdravlje ljudi, a vezani su uz pogoršanje socijalnih i gospodarskih uvjeta života. U okoliš s magmom uz vodenu paru (H2O), na površinu dospijevaju plinovi ugljikov dioksid (CO2) i sumporv dioksid (SO2), ugljikov monoksid (CO), vodikov sulfid (H2S), ugljikov sulfid (CS), ugljikov disulfid (CS2), klorovodik (HCl), vodik (H2), metan (CH4), fluorovodik (HF), bromovodik (HBr) i različiti organski spojevi te teški metali (živa, olovo, zlato). Njihovi nepovoljni učinci ovise o udaljenosti od vulkana te o eruptivnim obilježjima, tj. o viskozitetu magme i koncentraciji plinova. Štetnosti bliže vulkanu uključuju piroklastične rijeke, rijeke blata, plinova i vodene pare, potrese, zračne udare i tsunami. U štetnosti u udaljenim područjima ubrajaju se učinci toksičnosti vulkanskog pepela i zdravstveni problemi vezani uz dišni sustav, oči, kožu, zatim psihološke posljedice, ozljede, komunikacijski i transportni problemi, problem odlaganja otpada i opskrbe vodom, rušenje kuća, kao i pad strujnog napona. Dolazi do pogoršanja kvalitete vode i smanjenja kišnih razdoblja, oštećenja poljoprivrednih usjeva, uništavanja vegetacije. Za vrijeme vulkanskih erupcija i neposredno nakon njih povećan je morbiditet, posebno od respiratornih bolesti, a povećan je i mortalitet osoba zahvaćenih vulkanskom erupcijom. Nepovoljni zdravstveni učinci mogu se djelomično prevenirati pravodobnom primjenom zaštitnih mjera.

Abstract:

Speciation of inorganic sulfur species, mainly pyrite and metastable iron sulfides by operationally defined methods, is widely used for risk assessment of acid sulfate soils by quantifying the acidity producing elements, as well as for general characterisation of marine sediments and subaqueous soils. “Traditional” sulfur speciation methods commonly use highly specialised glassware which can be cumbersome for the operator, or, require long reaction times which limit the usability of the method. We present a simplified method which has a sufficiently low limit of detection (0.002%) and quantitation (0.006%) required for the analysis of sulfidic sulfur in acid sulfate soil materials. Commercially available sulfide reagents were used for determining reproducibility and the method was assessed on natural sulfidic soil materials, including fine to coarse grained soil materials as well as sulfide bearing peat, with a large variation of metastable sulfide and pyrite content.

Nano-sized cadmium sulfid (CdS) was synthesized successfully by a simple method using ultrasonic irradiation in the presence of polyethylene glycol (PEG 2000). X-ray diffraction (XRD) and transmission electron microscope (TEM) were used to characterize the structure and morphology synthesized powder. The nanocrystaline of β-CdS was grown in face-centered cubic. The average particle size of synthesized CdS is ~25 nm. CdS suspensions have then been impregnated on cotton-based textile samples and the antibacterial activity of so-functionalized textiles has been studied with respect to E. coli. Results shows that CdS nanoparticles exhibit a strong antibacterial activity and can inhibit 97% of growth E. coli bacteria.

Abstract:

Sulfites and sulfides are produced by yeasts in different amounts depending on different factors, including growth medium and specific strain variability. In natural must, some strains can produce an excess of sulfur compounds that confer unpleasant smells, inhibit malolactic fermentation and lead to health concerns for consumers. In organic wines and in sulfite-free wines the necessity to limit or avoid the presence of sulfide and sulfite requires the use of selected yeast strains that are low producers of sulfur compounds, with good fermentative and aromatic aptitudes. In the present study, exploiting the sexual mass-mating spores’ recombination of a native Saccharomyces cerevisiae strain previously isolated from grape, three new S. cerevisiae strains were selected. They were characterized by low sulfide and sulfite production and favorable aromatic imprinting. This approach, that occurs spontaneously also in nature, allowed us to obtain new native S. cerevisiae strains with desired characteristics that could be proposed as new starters for organic and sulfite-free wine production, able to control sulfur compound production and to valorize specific wine types.

Bioleaching/minerals biooxidation and bioremediation have been widely used commercially for heap/dump bioleaching of secondary copper sulfide ores, sulfidic-refractory gold concentrates and treatment of acid rock drainage. Technical and commercial challenges, identified in this paper, remain for bioleaching of primary sulfides and complex ores. New frontiers for the technology exist in processing massive sulfides, silicate-locked minerals and in the more distant future in-situ leaching. Decommissioning of cyanide heap leach operations and stabilizing mine wastes using biotechnology are opportunities requiring intensive and focused research, development and engineering efforts.

Abstract:

Experimental evidence suggests that nitric oxide (NO) and hydrogen sulfide (H2S) signaling pathways are intimately intertwined, with mutual attenuation or potentiation of biological responses in the cardiovascular system and elsewhere. The chemical basis of this interaction is elusive. Moreover, polysulfides recently emerged as potential mediators of H2S/sulfide signaling, but their biosynthesis and relationship to NO remain enigmatic. We sought to characterize the nature, chemical biology, and bioactivity of key reaction products formed in the NO/sulfide system. At physiological pH, we find that NO and sulfide form a network of cascading chemical reactions that generate radical intermediates as well as anionic and uncharged solutes, with accumulation of three major products: nitrosopersulfide (SSNO−), polysulfides, and dinitrososulfite [N-nitrosohydroxylamine-N-sulfonate (SULFI/NO)], each with a distinct chemical biology and in vitro and in vivo bioactivity. SSNO− is resistant to thiols and cyanolysis, efficiently donates both sulfane sulfur and NO, and potently lowers blood pressure. Polysulfides are both intermediates and products of SSNO− synthesis/decomposition, and they also decrease blood pressure and enhance arterial compliance. SULFI/NO is a weak combined NO/nitroxyl donor that releases mainly N2O on decomposition; although it affects blood pressure only mildly, it markedly increases cardiac contractility, and formation of its precursor sulfite likely contributes to NO scavenging. Our results unveil an unexpectedly rich network of coupled chemical reactions between NO and H2S/sulfide, suggesting that the bioactivity of either transmitter is governed by concomitant formation of polysulfides and anionic S/N-hybrid species. This conceptual framework would seem to offer ample opportunities for the modulation of fundamental biological processes governed by redox switching and sulfur trafficking.

Abstract:

Environmental context Remediation technologies often rely on manipulation of redox conditions or natural redox processes to favour microbial sulfate-reduction and mineral sulfide formation for treatment of inorganic contaminants in groundwater, including nickel. However, few data are available on the structural properties, solubility and mineral transformation processes involving nickel sulfides. These data are needed in order to constrain the long term performance of groundwater remediation efforts. Abstract The formation of nickel sulfides has been examined experimentally over the temperature range from 25 to 60°C. At all conditions studied, hexagonal (α-NiS) was the initial precipitate from solution containing Ni2+ and dissolved sulfide. Freshly precipitated nickel sulfide possesses significant residual Ni–O coordination as revealed by X-ray absorption spectroscopy. With progressive aging, residual Ni–O coordination is replaced by Ni–S coordination. The formation of millerite (β-NiS, rhombohedral) was not detected in any of the synthesis experiments. In the presence of elemental sulfur, hexagonal NiS converted to polydymite (Ni3S4) and vaesite (NiS2). Thus, conversion of nickel monosulfide to thiospinel and disulfide structures appears to be redox dependent, analogous to aging and transformation processes of iron sulfides. In the absence of elemental sulfur or with only hydrogen sulfide or bisulfide present, transformation of hexagonal NiS was not observed after 1680 h at 60°C. Low-pH solubility experiments yielded a solubility product for hexagonal NiS of log Ks0 = –2.69 ± 0.26. Solubility data at pH > 3 suggest that Ni–bisulfide complexation is important in controlling the solubility of Ni in sulfidic solutions.

Abstract:

Due to a combination of river regulation, dryland salinity and irrigation return, lower River Murray floodplains (Australia) and associated wetlands are undergoing salinisation. It was hypothesised that salinisation would provide suitable conditions for the accumulation of sulfidic materials (soils and sediments enriched in sulfides, such as pyrite) in these wetlands. A survey of nine floodplain wetlands representing a salinity gradient from fresh to hypersaline determined that surface sediment sulfide concentrations varied from <0.05% to ~1%. Saline and permanently flooded wetlands tended to have greater sulfide concentrations than freshwater ones or those with more regular wetting–drying regimes. The acidification risk associated with the sulfidic materials was evaluated using field peroxide oxidations tests and laboratory measurements of net acid generation potential. Although sulfide concentration was elevated in many wetlands, the acidification risk was low because of elevated carbonate concentration (up to 30% as CaCO3) in the sediments. One exception was Bottle Bend Lagoon (New South Wales), which had acidified during a draw-down event in 2002 and was found to have both actual and potential acid sulfate soils at the time of the survey (2003). Potential acid sulfate soils also occurred locally in the hypersaline Loveday Disposal Basin. The other environmental risks associated with sulfidic materials could not be reliably evaluated because no guideline exists to assess them. These include the deoxygenation risk following sediment resuspension and the generation of foul odours during drying events. The remediation of wetland salinity in the Murray–Darling Basin will require that the risks associated with disturbing sulfidic materials during management actions be evaluated.

Abstract:

A low-temperature precursor sulfuration route has been established to prepare metal sulfides with different nanostructures during the synthesis of nickel sulfide. The advantages of the low-temperature precursor sulfuration route were testified by the synthesis of different metal sulfides ( lead sulfide, zinc sulfide and cobalt sulfide). It offers a novel path to the preparation of other metal sulfides.

Abstract:

Sulfides in upper mantle lherzolite xenoliths from Cretaceous alkaline-ultramafic rocks in the Jetty Peninsula (East Antarctica) were studied for their major and trace-element compositions using SEM and LA-ICP-MS applied in situ. Modal abundance of sulfides is the lowest in Cpx-poor lherzolites ≤ Spl-Grt lherzolites << Cpx-rich lherzolites. Most sulfides are either interstitial (i-type) or inclusions in rock-forming minerals (e-type) with minor sulfide phases mostly present in metasomatic veinlets and carbonate-silicate interstitial patches (m-type). The main sulfide assemblage is pentlandite + chalcopyrite ± pyrrhotite; minor sulfides are polydymite, millerite, violarite, siegenite, and monosulfide solution (mss). Sulfide assemblages in the xenolith matrix are a product of the subsolidus re-equilibration of primary mss at temperatures below ≤300 °C. Platinum group elements (PGE) abundances suggest that most e-type sulfides are the residues of melting processes and that the i-type sulfides are crystallization products of sulfide-bearing fluids/liquids. The m-type sulfides might have resulted from low-temperature metasomatism by percolating sulfide-carbonate-silicate fluids/melts. The PGE in sulfide record processes are related to partial melting in mantle and intramantle melt migration. Most other trace elements initially partitioned into interstitial sulfide liquid and later metasomatically re-enriched residual sulfides overprinting their primary signatures. The extent of element partitioning into sulfide liquids depends on P, T, fO2, and host peridotite composition.

Abstract:

Inhibitor addition is one of the common corrosion control methods. Potassium metavanadate (KVO3) is the common corrosion inhibitor for Benfield solution in CO2 absorber. Former research shows that KVO3 is also able to inhibit the corrosion in seawater containing Sulphate Reducing Bacteria (SRB) due to its capacity as biocide. Chloride and Sulfide are common corrosive ions found in process fluids in industries. Therefore, this research is carried out to study the performance of KVO3 as a corrosion inhibitor for low- carbon steel in chloride and sulfide contaminated environment. The objective of this research was achieved by measuring low-carbon steel corrosion rate in various concentrations of contaminants. The corrosion rate was measured by Tafel method. The corrosion inhibition mechanisms were studied using cyclic voltammetry method. Meanwhile the corrosion products were identified by X - ray diffraction spectrometry (XRD). This research results that KVO3 is an effective corrosion inhibitor in chloride environment when the chloride concentration ranges between 20 g/L and 30 g/L. In this range of concentration, KVO3 performs more than 99% efficiency. While in sulfide environment, KVO3 is an ineffective corrosion inhibitor. On the other hand, the addition of KVO3 reduces the corrosion rate of carbon steel in seawater containing sulfide, although its performance does not meet the effective inhibitor criteria. Higher concentration of sulfide results the higher inhibition efficiency of KVO3.Keywords: Potassium metavanadate, low - carbon steel, corrosion inhibitor AbstrakPenambahan inhibitor merupakan salah satu metode pengendalian korosi. Kalium metavanadat (KVO3) sering digunakan sebagai inhibitor korosi pada absorber CO2 yang menggunakan larutan Benfield. Hasil penelitian sebelumnya menunjukkan bahwa KVO3 mampu menginhibisi korosi baja karbon rendah dalam air laut yang mengandung bakteri pereduksi sulfat (SRB) dengan bertindak sebagai biosida. Klorida dan sulfida merupakan ion-ion korosif yang umum ditemui dalam fluida proses di industri. Penelitian ini dilakukan untuk mempelajari kinerja KVO3 sebagai inhibitor korosi baja karbon rendah dalam lingkungan akuatik yang terkontaminasi klorida, ataupun sulfida. Untuk mencapai tujuan tersebut dilakukan pengukuran laju korosi baja karbon rendah dengan jenis dan konsentrasi kontaminan bervariasi. Pengukuran laju korosi dilakukan dengan metode Tafel. Mekanisme inhibisi diprediksi dengan metode voltametri siklik. Sedangkan produk korosi diidentifikasi dengan menggunakan spektrometri difraksi sinar X (XRD). Dari penelitian ini, diperoleh hasil bahwa KVO3 efektif sebagai inhibitor korosi baja karbon rendah pada lingkungan klorida berkonsentrasi antara 20 g/L hingga 30 g/L dengan efisiensi di atas 99%. Pada lingkungan sulfida, KVO3 kurang efektif menginhibisi korosi baja karbon rendah. Sedangkan pada air laut sintetik yang mengandung sulfida, walaupun belum termasuk kategori inhibitor efektif, namun KVO3 dapat menurunkan laju korosi baja karbon dengan efisiensi inhibisi yang meningkat seiring dengan kenaikan konsentrasi sulfida.Kata kunci: kalium metavanadat, baja karbon rendah, inhibitor korosi

Abstract:

ABSTRACT Observations in enrichment cultures of ferric iron-reducing bacteria indicated that ferrihydrite was reduced to ferrous iron minerals via sulfur cycling with sulfide as the reductant. Ferric iron reduction via sulfur cycling was investigated in more detail with Sulfurospirillum deleyianum, which can utilize sulfur or thiosulfate as an electron acceptor. In the presence of cysteine (0.5 or 2 mM) as the sole sulfur source, no (microbial) reduction of ferrihydrite or ferric citrate was observed, indicating that S. deleyianum is unable to use ferric iron as an immediate electron acceptor. However, with thiosulfate at a low concentration (0.05 mM), growth with ferrihydrite (6 mM) was possible and sulfur was cycled up to 60 times. Also, spatially distant ferrihydrite in agar cultures was reduced via diffusible sulfur species. Due to the low concentrations of thiosulfate, S. deleyianum produced only small amounts of sulfide. Obviously, sulfide delivered electrons to ferrihydrite with no or only little precipitation of black iron sulfides. Ferrous iron and oxidized sulfur species were produced instead, and the latter served again as the electron acceptor. These oxidized sulfur species have not yet been identified. However, sulfate and sulfite cannot be major products of ferrihydrite-dependent sulfide oxidation, since neither compound can serve as an electron acceptor for S. deleyianum. Instead, sulfur (elemental S or polysulfides) and/or thiosulfate as oxidized products could complete a sulfur cycle-mediated reduction of ferrihydrite.

Abstract:

The relative significance of different inorganic and organic sulfur compounds on the sulfide production in anaerobic biofilms grown on domestic wastewater was investigated. The objective was to improve the understanding of microbial processes in dynamic systems and to evaluate the equations used to predict sulfide formation in pressure mains. Biofilms originally grown on domestic wastewater with sulfate as the only electron acceptor were also able to reduce sulfite and thiosulfate. The bacteria preferred thiosulfate to sulfate if both were present and the sulfide production rates increased with a factor of 1.5. Disproportionation of thiosulfate to equal amounts of sulfide and sulfate was demonstrated to take place in the biofilms but only at low concentrations of organic substrates. Some sulfide production from the organic sulfur compounds cysteine and methionine was observed. The rates were, however, insignificant compared to sulfide production from sulfate reduction in wastewater. Biofilm activity measured as the zero order volume constant (kof) was around 0.18 mg SO4-S cm−3 h−1 at 20 °C. If the biofilms were grown on domestic wastewater enriched with sulfite or thiosulfate, kof increased around two times. The sulfide production rate from both sulfite and thiosulfate was found to be considerably higher than the rate from sulfate in these biofilms. The results were modeled using biofilm kinetics which showed that the presence of sulfite or thiosulfate in the wastewater strongly affected the potential sulfide production and could in some cases be a limiting compound besides organic matter. Knowledge about the presence of sulfur compounds other than sulfate in wastewater, e.g. from industrial sources, may therefore be very important to forecast sulfide buildup in sewer systems.

The morphology of sulfide and abrasive resistance of a high sulfur alloy steel cast at different cooling rate were investigated in this paper. The size, volume fraction and distribution of sulfides was decreased as the solidification rate was increased. After heat treatment, many spherical sulfide were found. Most of sulfides within grains were Cr2MnS4, while sulfides at grain boundaries were mainly FeS. High sulfur alloy steel had strong abrasive resistance.

Abstract:

Soil micromorphology, using light microscopy and scanning electron microscopy (SEM), was used to describe detailed soil morphological and compositional changes and determine mineral weathering pathways in acid sulfate soils (ASS) from the following 2 contrasting coastal environments in Barker Inlet, South Australia: (i) a tidal mangrove forest with sulfidic material at St Kilda, and (ii) a former supratidal samphire area at Gillman that was drained in 1954 causing sulfuric material to form from sulfidic material. Pyrite framboids and cubes were identified in sulfidic material from both sites and are associated with sapric and hemic materials. Gypsum crystals, interpreted as a product of sulfide oxidation, were observed to have formed in lenticular voids within organic matter in the tidal mangrove soils at St Kilda. Sulfide oxidation was extensive in the drained soil at Gillman, evidenced by the formation of iron oxyhydroxide pseudomorphs (goethite crystallites and framboids) after pyrite and jarosite, and of gypsum crystals. Gypsum crystals occur where a local source of calcium such as shells or calcareous sand is present. Sporadic oxidation episodes are indicated by the formation of iron oxide and jarosite coatings around coarse biogenic voids. These observations indicate that mineral transformation pathways are strongly influenced by soil physico-chemical characteristics (i.e. oxidation rate, Eh, pH, soil solution chemistry, mineralogy, and spatial distribution of sulfides). This information has been used to illustrate the interrelationships of pyrite, carbonate, gypsum, jarosite, and organic matter and help predict soil evolution under changing hydro-geochemical, redoximorphic, and thermal conditions in soils from coastal environments.
