Abstract

The present study investigates the degradation of Acid Red 14 (AR14), commonly used as a textile dye in aqueous medium through the oxidation process by UV /S2O82- under a set of variables concentration of S2O82-, Ag+, AR14 and temperature. Commonly Ag+, heat and UV light can excite S2O82- to sulfate radical form (SO4-), a stronger oxidant (E0=2.60 V) than S2O82-, to enhance significantly the oxidation of contaminants. Also the changes in the absorption spectra of AR14 solutions during the photoxidation process showed that decrease of absorption peak of the dye at lmax=514 nm indicates a rapid degradation of the azo dye. The results of this study suggest that the oxidative treatment of AR14 by PEROXYDISULFATE with UV is a viable option for removal of the textile dyes from effluents.
