It is a challenging process for degrading anthropogenic sources of heavy metals and toxic organic compounds in water at the same time. In this work, redox cycle of Fe3+/Fe2+ was utilized as a photocatalyst for the simultaneous reduction of chromate and oxidation of aromatic compounds in aqueous suspension under UV irradiation. The photocatalytic efficiency of the oxidation was enhanced in the presence of chromate due to its efficient interaction with the degradation intermediates. Increase in concentration of iron which further produces OH? radicals and presence of oxygen which recycles iron through the system enhance both reactions. The removal of organic compounds with simultaneous reduction of chromate was achieved. This study provides an efficient photocatalytic system for the treatment of wastewater co-contaminated with heavy metals and organic compounds.
