Reactive dye make the problem in solution because it can’t degradation by microorganisme so that the dye still remained in solution. Therefore, the removal of dyes from solution before disposal process is an important aspect. Decolorization of aqueous solutions containing an azo dye (Remazol Red B) was achieved by advanced oxidative process using Fenton reagent. The optimum amounts of Fenton reagent was 1,25 mg/L of Fe2+ and 25 mg/L of H2O2 for an initial Remazol Red B at 83 mg/L. The ratio of H2O2/Fe2+ equal to 20 to give the best result for the decolorization efficiency. The optimum conditions of Fenton reaction obtained at pH 3 and a temperature of 300 K and the decolorization efficiency of Remazol Red B attained 100% for 55 min reaction time. Kinetics decolorization of Remazol Red B followed second-order reaction. Metal ions i.e. Cu2+, Pb2+ and Zn 2+ did not affect the process of degradation reactions in Fenton.
