    Abstract

    The objective of this study is to determine the influence of various parameters on the degradation of dye (with high COD value) by using Fenton process. Design of experiment was applied for the optimization with respect to: initial concentration of Fe2+ and H2O2 to ascertain their respective effects on the treatment efficiency. The progress of dye degradation was analyzed by monitoring the Chemical Oxygen Demand (COD). The experimental results show that the initial concentration of H2O2, and Fe2+, had great influence on degradation of dye by Fenton process. Application of optimum operation conditions of: Fe2+/Dye = 10 and Fe2+/H2O2= 25 at constant pH=3, mineralization of 78% was achieved for the dye with initial COD value of 1228 mg/L. Based on the degradation effciency , the optimized initial concentration of Fe2+ and H2O2 has a proven influence in treatment of waste water with high COD value by Fenton process.
