Description
When an aqueous solution of Na2[Mo(V)2O4EDTA] (ethylene diamine tetra acetate) was photolyzed in the presence of excess KBr and K2S2O8 at neutral pH, the complex was found to be oxidized due to the reactions of Br2- and SO4-, respectively. Oxidation of the complex was also observed due to the reactions of the complex with radiolytically generated Br2- and SO4- radicals. When the oxidation of the complex with SO4- was conducted in an unbuffered solution, a chain reaction was observed in the oxidation of the complex. The time resolved kinetics for the formation and decay of different transient intermediates and the relevant rate constants were investigated with a flash photolysis technique, and a probable mechanism for the oxidation process was given.
