In this study, the decolorization of Acid Blue 92 (AB-92), a commercially important azo dye, by Fenton’s oxidation was investigated. The effect of operating parameters, such as initial pH, dosages of Fe2+ and H2O2, dye concentration on the color removal was studied. The optimum conditions were determined as pH = 5, [Fe2+]= 5 mg/L, [H2O2] = 2260 mg/L, [AB-92] = 20 mg/L and for 3 min reaction time. Maximum decolorization (97%) efficiencies were achieved at optimal condition.
