In this paper, removal of Rhodamin B in the semi batch reactor (SR) has been studied by considering the effects of operating parameters such as PH, catalyst dosage, H2O2 concentration and temperature effects occurred with UV irradiation process. The reaction rate and efficiency increase with increasing temperature, it indicates that the reaction is endothermic, this can be explained using the constant parameter of rate, K=exp-E/RT.
