Oxidation by photo-Fenton reaction is an economically feasible process for degradation of a variety of hazardous pollutants in wastewater fromdyeing and printing industries. Oxidation of Congo Red (CR) using photo-Fenton reagent has been carried out under ambient condition. The effect of different parameters like the concentration of Fe2+, initial concentration of (CR) dye,pH,hydrogen peroxide are studied and optimal condition are reported. The photo-Fenton degradation process was monitored by HPLC and UVvisible spectroscopy.
