Abstract:

Precious metal Pd are widely used in high-tech industries due to their scarcity and special properties. In this paper, 2-methylimidazole zinc salt (ZIF-8)/PVDF hybrid membrane was successfully synthesized by self-assemble method. The effect of polyarcylic acid sodium (PAAS) and polyethyleneimine (PEI) as complexing agents was investigated. The rejection rate of hybrid membrane under different polyelectrolyte-metal complexing ratios and their extraction performance under different concentration were examined.

Abstract:

Majority of lead content found in the environment is the result of human activities. Heavy metals can be hazardous because they tend to bioaccumulate. Complexation-microfiltration process for the removal of Pb(II) ions was studied. The aim of microfiltration of the model wastewater containing heavy metal ions was finding an optimum ratio between the concentrations of the complexing agent and metal, and determining the most favorable pH value. The microfiltration experiments were carried out in a stirred dead-end cell. Diethylaminoethyl cellulose (DEAE 23) was selected as the complexing agent.

Among the methods for removing heavy metal ions, the sorption and ion exchange are the most attractive if the sorbents and ion exchangers are inexpensive and effective.

Abstract:

Effective molecular imaging and targeted cancer therapy rely on receptor-specific targeted delivery systems that are both metabolically stable and kinetically inert for optimal in vivo performance. Until now, no single metal complexing agent has demonstrated the versatility to coordinate metals across the periodic table while maintaining the kinetic inertness required for clinical theranostic applications. Therefore, enhancing the in vivo kinetic stability of radiolabeled, cell-targeting, biologically active compounds remains a critical goal to minimize unintended accumulation of radioactivity

Lacquered brass objects are widely present in scientific and technical heritage collections. Localized atmospheric corrosion occurs on the metal when the coating fails to play its protective role. Although lacquered brass objects are not necessarily endangered by this phenomenon, the presence of dark, unpleasant corrosion spots alters the surface appearance, affecting the readability of the objects. Conservators are therefore frequently asked to clean these surfaces. We hereby present the results of a study conducted in the framework of the CleanLaB (Cleaning of Lacquered Brass) project at the

Currently, in colorimetric analysis, the concentration of Mn ion is determined using its characteristic color. However, few metal ions produce such strong colors, especially at low concentrations. Many colored complexes can be formed from metal ions and organic or inorganic complexing agents.

An ideal color-forming reagent requires that it be stable and selective (even specific) and that it reacts rapidly to form soluble, highly colored complexes.

It has been established in laboratory model experiments that the removal of dissolved heavyimetals from wastewaters is rendered more difficult in the presence of colloid-stabilizing agents.

By increasing the concentration of Mg2+ ions, the pH necessary for destroying the stability of colloidal dispersion can be lowered. These findings also apply to the combined removal of different heavy metals (Cu, Zn, Cr(III), Ni, Cd). In alkaline conditions, in the presence of ammonium salts, some

Abstract:

Synthesis of copolymers from carbon dioxide (CO2) and epoxides is an important research direction as such processes utilize the abundant greenhouse gas and deliver useful products. Specifically, cooligomers of CO2 and propylene oxide (PO) with a non-alternating structure can be used for polyurethane preparation. They are synthesized by employing Zn-Co cyanide catalysts. The application of alternative metal cyanide complexes is interesting from scientific and practical points of view. The purpose of this work was to study the copolymerization of CO2 and PO in the presence of Co-Ni cyanide catal

Abstract:

Calixarenes represent a well-known family of macrocyclic molecules with broad range of potential applications in chemical, analytical, and engineering materials fields. This paper covers the use of calixarenes as complexing agents for uranium(VI). The high effectiveness of calix[6]arenes in comparison to other calixarenes in uranium(VI) separation process is also presented. Processes such as liquid-liquid extraction (LLE), liquid membrane (LM) separation, and ion exchange are considered as potential fields for application of calixarenes as useful agents for bindingUO22+for effective separation

Abstract:

Abstract Of two sensitive complexometric reagents for the colorimetry of serum zinc that we investigated, one, 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (Br-PADAP), was found to be a potentially useful compound for trace-metal determinations. It has a high molar absorptivity (120 000 L mol-1 cm-1) but is not convenient to use because it is not very soluble in water. The other reagent, a related pyridylazo compound, is 2-(5-bromo-2-pyridylazo)-5-(N-n-propyl-N-3-sulfopropylamino)phenol (5-BR-PAPS). It seems better suited for use in routine zinc determinations because, besides being water sol

Abstract:

Large lignite reserves are concentrated in the Dnipro lignite basin of Ukraine. It is profitable to extract it by open-pit mining, as the seams are shallow. Ukrainian lignite is predominantly earthy, subbituminous, which in turn is characterized by a high content of free humic acids. Despite the significant lignite reserves in Ukraine and favourable conditions, its production is insignificant. Most of the lignite is used as fuel, and a small part of it is used as raw material. We have studied the lignite of the Oleksandriya deposit of Ukraine, which contains a large amount (about 80 %) of humi

Abstract Cu-doped ZnS was synthesized as a new photocatalyst material by electrodeposition. We attempted to synthesize ZnS using electrolytic baths containing metal ions and various complexing agents, i.e. tartaric acid, citric acid, triethanolamine (TEA), and disodium ethylenediaminetetraacetic acid (EDTA-2Na). The crystalline properties, binding conditions, surface morphology, and chemical composition of the samples were examined by X-ray diffraction, Raman spectroscopy, scanning electron microscopy, and energy dispersive spectrometry, respectively. ZnS was synthesized from all electrolytic
