Abstract

In this study, the decolorization of an azo dye Orange G (OG) by homogeneous advanced oxidation processes was investigated in the presence of persulfate (S2O82−) and periodate (IO4) under UV irradiation at 254 nm in aqueous solution. The obtained results showed that the decolorization of OG increased in the UV/S2O82− and UV/IO4 systems compared to the UV system alone. In both cases (UV/S2O82− and UV/IO4), the increase in the oxidant concentration enhanced the dye decolorization rate. However, a higher degradation activity was observed when IO4 was added to the solution.
