Studies on Chromate Removal by Chromium-Resistant Bacillus sp. Isolated from Tannery Effluent
Bacillus sp. Bioremediation Cr (VI) Removal Tannery Effluent
2013/3/12
A chromate-removing strain was isolated from spent chrome effluent and identified as Bacillus circulans strain MN1. The isolated strain was studied for resistance to Cr (VI) and its ability to remove ...
High hydrostatic pressure and chromate-induced effects on cell cycle kinetics
cell cycle kinetic chromate Glioma animal
2009/7/14
Cell cycle kinetics was studied using the quenching of 33258 Hoechst fluorescence by bromodeoxyuridine incorporation to investigate effects of high pressure on the toxicity of a welding fume component...
High hydrostatic pressure potentiation of the toxic effects of chromate in cell culture
human chromate cell culture commercial welding
2009/7/14
Development of hyperbaric welding has created the need for new occupational health standards. We have used cell cultures to investigate effects of high pressure chromate on the toxicity of the welding...
The reduction of chromate ions by Fe(II) layered hydroxides
chromate ions Fe(II) layered hydroxides
2009/5/27
The reduction of chromate ions by Fe(OH)2 and the iron (II)-iron (III) hydroxysulphate green rust, GR(SO42-), was studied to evaluate whether such synthetic layered hydroxides and the corresponding na...

Application of Potassium Chromate-Diphenylcarbazide in the Quantitative Determination of Ascorbic Acid by Spectrophotometry
Ascorbic acid determination Spectrophotometry Potassium chromate Chromium-diphenyl-carbazide complex
2010/4/21
A spectrophotometric procedure for the determination of ascorbic acid in pure form and in a number of pharmaceutical preparations and real samples has been developed that offers the advantages of simp...
Adsorption of Arsenate and Chromate from Waters on Hydrophobized Zeolitic Media
Octadecylammonium-clinoptilolite adsorption anion-exchange chromate and arsenate oxyanions montmorillonite
2010/4/21
A laboratory setup was used to examine the uptake of chromate and arsenate from aqueous solutions by octadecylammonium acetate [ODA]-modified inland clinoptilolite. In trials, a natural variety of mon...
Chromate Removal by Dithionite-Reduced Clays: Evidence from Direct X-Ray Adsorption Near Edge Spectroscopy (Xanes) of Chromate Reduction at Clay Surfaces
Illite IMt-2 Kaolinite KGa-2 Montmorillonite Reduction Smectite Sorption SWa-1 SWy-1 XANES
2011/12/6
Abstract: Chromium(VI) in the environment is of particular concern because it is toxic to both plants and animals, even at low concentrations. As a redox-sensitive element, the fate and toxicity of ch...
Chromate (CrO42-) adsorption was investigated on kaolinite (0.2? 祄) saturated with NaClO4 over a range of pH. Adsorption increased with decreasing pH because of protonation of chromate and/or variable...
