【Abstract】 The photolysis of Fe(Ⅲ)-Oxalate complexes can produce Oxidant H 2O 2 and ·OH radicals, which can destroy the organic compounds’ structure. Photodegradation of dye Orange Ⅱ in aqueous solutions was investigated. Effects of the pH, dye concentration and the radio Fe(Ⅲ)/Oxalate on photodegradation rates were examined. The preliminary mechanism of Orange Ⅱ photodegradation was inspected through UV-VIS spectra analysis.更多还原
