Abstract

In this work, the photolysis of ferrioxalate complexes  attended to the photoreduction of hexavalent chromium  has been studied kinetically and mechanistically in aqueous solutions, under UV/Visible irradiation .

The results showed, that the iron(III) undergoes rapid photoreduction to iron(II), occompanied by oxidative degradation of oxalic ligands to carbon dioxide .

Photochemically generated  is readily reoxidized to  by the present  in the deaerated - system, thus the  is reduced to at last.

In addition, kinetics of the overall occurring photoreaction has been discussed, and its probable mechanism has been suggested under the experimental conditions employed.
