Abstract

Application of photo-Fenton process, UV/Fe3+/H2O2, to treatment for a mixture of three cationic dyes was investigated. The effect of the oxidative agent's initial concentration was investigated as well as the effect of the initial concentration of Fe+3 and H2O2 on the dyes degradation was studied. The best results were obtained using 0.6 mM of Fe3+ and 12 mM hydrogen peroxide. Under these experimental conditions, 90% of TOC and 100% of color removal were achieved.
