In this work, The degradation of the methyl orange (MO) dye was studied using advanced oxidation process (AOP) by exposing MO aqueous solution to UV irradiation after the addition of hydrogen peroxide (H2O2). The degradation of MO was accompanied by the decolorization of the solution. A thorough investigation of the AOP process was carried out by studying the influence of the dye concentration, H2O2 concentration, operation time, and pH. The result indicated that the maximum The degradation of the MO(91%) was achieved at pH 2.5. Also by increasing H2O2 concentration, the amount of The degradation of the MO increases. also color removal increased with increasing operation time. Advanced oxidation processes (AOPs) have proved very eﬀective in treatment of the various hazardous organic pollutants in water. This operetion has good efficiency for The degradation of th MO dye.
