Resumen

In this work the issue of processing of dross with preliminary separation of the metal part from the oxide one is reviewed. Based on a comparative analysis of the results of known works it is shown that this approach can be quite effective if a technology is developed for the separate processing of the oxide part to obtain a commercial product. The authors of this work proposed carrying out chlorinating roasting under oxidizing conditions with various chlorine-containing reagents as one of the effective ways of processing the oxide part of the dross. Based on the thermodynamic analysis of the

Resumen

Chlorine is a critical element with respect to the use of fossil fuel, recycling of industrial wastes, and water purification. Chlorine could form toxic chemical compounds, corrode pipe systems and boilers, and contaminate surface and ground waters. Calcium aluminate-layered double hydroxides are one of the most promising materials to remove chlorides due to the chemisorption mechanism, since the phases have positively charged interlayers. Many studies on the synthesis and the characterization of calcium aluminate-layered double hydroxides have been extensively conducted, whereas few studies h

Resumen

Calcium exists in several compounds, calcite (CaCO3), dolomite (CaMg (CO3)2), calcium oxide (CaO) and calcium chloride dihydrated (CaCl2, 2H2O). All of these calcium compounds occur in oil shale. This work consists of using some physical and reaction analytical methods to try to discernthese calcium constituents quantitatively. By the methods of this work, which are the complexometry reaction using dimethyl tetra acetic acid (EDTA), the hydrochloric acid etching reaction and dispersive X-ray diffraction, we have tracked these calcium qualities.

Resumen

The voluntary intake by male Sprague-Dawley rats of five calcium salts and eight mineral chlorides was assessed. Groups of 12-25 rats received a series of 48-h two-bottle tests with a choice between water and ascending concentrations of a mineral solution. Similar inverted U-shaped concentration-intake functions were obtained with each of the five calcium salts tested (hydroxide, gluconate, phosphate, lactate, and chloride): rats drank more calcium solution than water at concentrations between approximately 0.2 and 5 mM, showed indifference between 5 and 12 mM, and avoided higher concentration

Resumen

The present work deals with the study of Chloride concentration of Nira River in the year 2016. Fresh water is essential to existence of life. Acceptable quality water is essential not only for drinking and domestic purposes but also for agriculture, industrial and commercial uses. Chloride occurs naturally in all types of water. In natural fresh water, the concentration is quite low. The important source of chloride in the water is the discharge of domestic sewage. Chlorides are highly soluble in water so they do not get precipitate and cannot be removed by biological treatment of water. If t

Resumen

To address the problem of chloride ion transport in cement concrete in marine environment, this study investigates the effect of metakaolin dosage on the chloride ion diffusion resistance of mortar and its mechanism by testing the chloride ion binding capacity and microstructure of mortar under the coupling effect of chlorine salt-sulfate-carbonation multiple factors. The results show that the coupling of sulfate or carbonation reduces chloride ion transport to some extent compared with single chlorine salt attack, while the three-factor coupled environment promotes free chloride ion diffusion

Resumen

Cement is primarily used in drilling operations to protect the casing against the corrosive tendency of formation fluid and to support the casing with the external load on and around it. Cement slurry is formed by mixing water with Portland cement or with cement containing various essential additives as the case may be and pumping it down through to critical points in the annulus around the casing using various techniques. Class G cement is widely used in cementing jobs because it allows the use of accelerators and retarders for wide range of well depths and temperatures. Due to wait-on-cement

For several decades, calcium chloride has been widely used as a cheap and effective accelerator. Calcium chloride is remarkably decreasing the initial and final setting times of concrete. It is mainly used at low-temperature concreting because it allows for earlier finishing and reduces the effects of water freezing inside fresh concrete. The use of calcium chloride in reinforced concrete has been decreased after identifying its effect on reinforcement corrosion. However, calcium chloride is still widely used in ordinary concrete and some reinforced concrete in specific proportions. This paper

Resumen

Calcium application trials were undertaken in a 'Braeburn' apple (Malus ×domestica Borkh.) orchard with a history of bitter pit development at harvest. In 2000, an early season calcium chloride application strategy was compared with the unsprayed control and a late season application strategy. From 2001–03, the assessment of timing of calcium chloride sprays was extended by comparing effects of five weekly sprays applied during the growing season either early, middle, or late season. Other Ca application strategies tested included sprays of acidified calcium carbonate suspensions and soil appl

Resumen

The chlorination of oxides of major concern in cassiterite concentrate with various chlorinating agents is investigated in light of their thermodynamic feasibilities to extract and recover their valuable metal components. Mechanisms responsible for the processes and their Gibbs free energy changes as a function of temperature to selectively separate and/or recover the metal(s) of interest and unwanted ones as their metallic chlorides are identified. Attention is given to gaseous (Cl2 and Cl2 + CO mixture) and solid (CaCl2 and MgCl2) chlorine sources, from which Cl2 + CO shows no reaction selec

Resumen

When either sulfate or chloride is added to the diet, the resulting acid load causes a rise in urinary calcium excretion. There is, however, the possibility that sulfate, which has been shown to complex renal tubular calcium, will further decrease renal calcium reabsorption and thus produce a greater calciuria than chloride. Because addition of a fixed cation (e.g., sodium) to the diet may also stimulate calciuresis, experiments were conducted using metabolizable ammonium to minimize cation effects. Ammonium salts of sulfate, chloride, and carbonate (control) were added to the diets of male ra

Resumen

This paper reports study findings on the diffusivity of chloride ions in potential blended cement. The cement, abbreviated as PCDC, was made from blending ordinary Portland cement (OPC) with dried calcium carbide residue and an incinerated mix of rice husks, spent bleaching earth, and broken bricks. The aim of the study was to investigate the ability of PCDC to withstand aggressive chloride environment. 10 cm × 10 cm mortar cubes were prepared using PCDC and cured for 28 days in saturated calcium hydroxide solution. The cured mortar cubes were subjected to aggressive chloride media in a labora

Resumen

Both calcium and caffeine induced calcium release from actively loaded heavy sarcoplasmic reticulum vesicles were studied to analyze the dependence of both activities on the composition of the release medium with respect to monovalent anions. Calcium is unable to induce net calcium release while caffeine remains effective as releasing agent when the experimental media contain neither chloride nor nitrate ions. Caffeine induced calcium release is not suppressed by chelating residual medium calcium (approximately 0 .5 -1 μᴍ) with 2 mᴍ EGTA added 15 s prior to 10 mᴍ caffeine. Calcium release from

Resumen

The excess of magnesium chloride brines is formed during the polymineral ores processing in order to obtain potassium sulfate. One way to regenerate such brines is to produce artificial carnallite. It is necessary to purify these brines from sulfates for their further use as raw materials for the artificial carnallite production. In this work, the process of desulfurization of magnesium chloride brines with a solution of calcium chloride is studied. The temperature and the processing time, the magnesium chloride solutions concentration and the consumption of desulfurizing agent (calcium chlori

Resumen

The role of extracellular chloride in the regulation of mesangial cell calcium responsiveness to vasopressor peptides was explored. First, the components of vasopressor-stimulated calcium signaling were defined in rat mesangial cells cultured on coverslips and preloaded with fura 2. By spectrofluorometry, manganese uptake (reflecting divalent cation channel activation) was observed by quenching of fura 2, or intracellular cytosolic calcium concentration was calculated by dual-excitation ratiometric measurement. In cells depolarized with KCl (45 mM), enhanced manganese uptake or increased cytos
