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 ...

Toxic and genotoxic effects of trivalent and hexavalent chromium - A review
(2005-06-01)
During the last years, the emission of heavy metals to the environment has increased, causing a severe negative impact to the ecosystems and seriously compromising human health due to their mutagenic potential. Tri- (III) ...

Reduction of hypervalent chromium in acidic media by alginic acid
(Elsevier, 2014-08-08)
Selective oxidation of carboxylate groups present in alginic acid by CrVI affords CO2, oxidized alginic acid, and CrIII as final products. The redox reaction afforded first-order kinetics in [alginic acid], [CrVI], and ...
