Photooxidation of Natural and Waste Cr(III)-Bearing Hydroxides in Water and Ice: Cr(III)-O2 Complex-Mediated Oxidation and the Effect of Natural Organic Matter
{{output}}
The photooxidative dissolution of Cr(III)-bearing hydroxides (Cr(OH)3 and FexCr1-x(OH)3) is proposed as a potential abiotic source of Cr(VI) in environments. Compared to the dark oxidation of Cr(OH)3 by O2, photoirradiation enhanced Cr(VI) production in both a... ...
