Abstract:

The most economically important iron-chromium bearing minerals is chromite. In natural deposits, iron(II) is frequently substituted by magnesium(II) while chromium(III) is replaced by aluminum(III) and/or iron(III) forming a complex chromium bearing material. The majority of mined chromite is intended for the production of ferrochrome which requires a chromite concentrate with high chromium-to-iron ratio. Found mostly in the spinel chromite structure, iron cannot be removed by physical mineral processing methods. In this frame, the present work deals with the reaction of chlorine and chlorine+

The presence of chromium in the environment poses a potential mutagenic hazard to all animal and plant life, including humans. Methods have been proposed for detecting the formation of chromium, isolating it, and recovering it from contaminated environmental samples. The permissible limits of chromium in environmental samples such as industrial waste, workplace particles, plants, aquatic animals, and food samples have been studied. A suitable organic reagent has been selected. A sorption spectroscopic method has been developed for the determination of chromium (III) in industrial effluents. An

The use of alkali aryloxide reagents in organo-metallic synthesis often depends on their solubility, a property derived from their structure. The regain of interest of alkali aryloxides also originates from the discovery of high-temperature superconducting compounds, which has generated a great interest in the formation of oxide materials and other ceramics. Thus, many alkoxides of yttrium and copper are common precursors for oxide materials. Moreover, the synthesis of heterobimetallic alkoxides has provided a facile route for obtaining soluble, volatile, and generally monomeric species. These

This model provides a quick and easy way of determining Cr(III) content in a tanning process having high chromium concentrations. Shifts of absorption peaks and changes in the intensity of absorption—due to different ligands of the chromium complex, aging, or differences in pH and temperature—all create difficulties in the modeling of a chromium-tanning solution.

Abstract:

This paper deals with the effect of supplementation with the three different preparations of organic chromium complexes: the ethylenediaminetetraacetic acid complex with chromium; chromium (III)?lysine and chromium picolinate, on broilers meat quality. In every preparation supplementing broilers diet chromium was present at the three different levels: 0.2; 0.4 and 0.6 mg/kg. The meat quality was monitored with respect to the following parameters: the contents of fat, protein, minerals and water. It was observed that the fat content in broilers white meat was significantly lower if their diet w

Abstract:

In the world, a large number of workers are exposed to fumes, mists and dusts containing Chromium and its compounds. One of the ways to prevent chromium intoxication is the enrichment of food rations with substances that have antioxidant and complexing ability. Attention is focused on the recommendations on the use of sulfur-containing amino acids and sulfur-rich proteins in the composition of food products for the prevention of intoxication in workers who come into contact with chromium in production. The mechanism of reduction of hexavalent chromium compounds by cysteine was considered. It h

Abstract:

Complex anions of Cr(III) analogues of Reinecke s salt, [Cr(NCS)4(amine)2] are good analytical reagents with high sensibility and selectivity for N-organic bases of pharmaceutical importance. We have observed that the phenothiazinic type drug, thioridazine, prescribed for the treatment of maniac-depressing psychosis precipitates with Cr(/11) complex anions. Some new oxidative methods for the determination of thioridazine (10-[2-(1-methyl-2-piperidinyl)ethyl]-2-(methylthio)-10H-phenothiazine) are described The results were evaluated statistically

Some concepts of green chemistry were applied on the Synthesis of Chromium(III) and Mo(V) complexes with amino acids. Three concepts were used in this research were changing to safer solvent, using less energy and appliying a shorter process. The optimum pH of the complex formation of Chromium (III) is 4, whereas for Mo(V) complex, the most stable condition is at pH=1. The products were characterized by physical properties, Infrared and Uv-Vis spectrophotometer, Atomic Absorbtion Spectrophotometer, Elemental Analysis, and VSM (Vibrational Sample Magnetometer).

Modified AC was used as low cost and effective solid phase extractor (SPE) for removal, total determination and chemical speciation of chromium(III&VI) in wastewater. Pseudo-second order rate equation is proposed for assigning the kinetics of chromium(VI) sorption in aqueous HCl (1.0 mol L-1) by PQ+Cl-- modified AC .

Abstract:

The aim of the study is to determine the effect of organic reductants (sawdust) on the degree of reduction of chromium (VI) ions in the complex processing of waste chromium-containing solution (electrolyte) of plating production, as at the same time to determine the optimum conditions of the process. Experimental results showed that organic reductants (sawdust, and lignin) in an acid environment work as a reagent-reductant of chromium (VI) ions. The process of reduction of chromium (VI) ions to chromium (III) proceeds intensively for the first 20-30 min and is completed within 50 minutes, whil

Abstract:

The role of direct photochemical reactions of Cr(VI) and Cr(III) species in the environmental degradation of organic matter was investigated by means of Cr(VI)/alcohol and Cr(III)/EDTA model systems under conditions mimicking the environmental ones. Photoreduction of Cr(VI) proceeds through reductive quenching of chromate(VI) excited within UV-A by an alcohol molecule. AlthoughHCrO4−is more susceptible to the quenching than theCrO42−ion, and oxygen favours the reverse reaction, the reduction can be easy noticeable at air-saturated natural waters.
