Redox and complexation chemistry of the CrVI/Cr V/CrIV-d-glucuronic acid system
(2010)
When excess uronic acid over CrVI is used, the oxidation of d-glucuronic acid (Glucur) by CrVI yields D-glucaric acid (Glucar) and CrIII as final products. The redox reaction involves the formation of intermediate CrIV and ...
Radiometric and spectrophotometric studies of the behavior of chromium(VI) oxide in concentrated perchloric acid
(R Oldenbourg VerlagMunchenAlemanha, 1997)
KINETIC AND EQUILIBRIUM STUDIES OF CR(III) AND CR(VI) SORPTION FROM AQUEOUS SOLUTION USING ROSA GRUSS AN TEPLITZ (RED ROSE) WASTE BIOMASS
(Sociedad Chilena de Química, 2008)
Optimization of Culture Conditions for Growth Associated with Cr(VI) Removal by Wickerhamomyces anomalus M10
(Springer, 2016-11)
Chromate-resistant microorganisms with the ability of reducing toxic Cr(VI) to less toxic Cr(III), are candidates for bioremediation. An alternative culture medium to reduce Cr(VI) using Wickerhamomyces anomalus M10 was ...
On-line preconcentration and speciation analysis of Cr(III) and Cr(VI) using baker's yeast cells immobilised on controlled pore glass
(Elsevier B.V., 2005-08-08)
A study was undertaken to evaluate Saccharonzyces cerevisiae as a substrate for the biosorption of Cr(III) and Cr(VI) aiming to the selective determination of these species in aqueous solutions. The yeast cells were ...
Sequential spectrophotometric determination of chromium(III) and chromium(VI) using flow injection analysis
(1985-12-01)
A flow injection analysis (FIA) procedure for the speciation of Cr(III) and Cr(VI) using the 1,5-diphenylcarbazide (DPC) method is presented. As Cr(III) does not interfere in the Cr(VI) - DPC reaction, both Cr(VI) and total ...
Cr(VI) and Cr(III) removal from aqueous solution by raw and modified lignocellulosic materials: a review
(Elsevier Science, 2010-08)
In aqueous systems, chromium usually exists in both trivalent and hexavalent oxidation states, being Cr(VI) of particular importance and concern due to its great toxicity. Industrial sources of Cr(VI) are leather tanning, ...
Textile-dye polluted waters as a source for selecting chromate-reducing yeasts through Cr(VI)-enriched microcosms
(Elsevier Sci, 2013-01)
Chromate-resistant microorganisms able to reduce toxic Cr(VI) into insoluble Cr(III) are seen as prom- ising candidates for alleviating Cr(VI)-contamination. In this study, chromate-reducing yeasts could be isolated from ...
Kinetics of Cr(III) and Cr(VI) removal from water by two floating macrophytes
(Taylor & Francis, 2016-10)
The aim of this work was to compare Cr(III) and Cr(VI) removal kinetics from water by Pistia stratiotes and Salvinia herzogii. The accumulation in plant tissues and the effects of both Cr forms on plant growth were also ...
