AbstractThe mineralization of C.I. Acid Orange 7 (AO7) azo dye by UV/H2O2 Advanced Oxidation Process was studied in a flux through annular photoreactor. An experimental design based on Response Surface Methodology (RSM) was applied to evaluate the simple and combined effects of influencing independent parameters on mineralization efficiency and optimising the operating conditions of the treatment process.

This paper deals with the advanced oxidation using Electro-fenton reagent for the degradation of azo-dyes in textile effluents. Discharge of textile effluents causes inevitable pollution of water resources which calls for further treatment methods. In this experiment, textile effluent samples were treated with iron electrodes with the reagents, hydrogen peroxide and ferrous sulfate .The acid dye effluents which were used in this study are Acid Orange 7, Acid Red 88, and Acid Violet 7. The temperature was set to 40° C. Samples of 20 ml were analyzed for Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Colour reduction. Experiments were carried out at voltage variations of 2, 4, 6 and 8 volts. From the results, COD and Colour were observed to be reduced drastically from respective original values before treatment with Fenton’s reagent using electro-chemical method.Keywords--- Advanced oxidation, Electro-fenton, BOD, COD, Colour reduction
