Abstract

Advanced Oxidation Processes (AOPs) are the effective processes in treatment of the various wastewaters contaminated with hazardous organic pollutants. In this work, DECOLORIZATION of Acid Blue 74 in the UV/H2O2 process by using a batch photochemical reactor equipped with a 15 W low pressure mercury lamp (Osram) and aeration system as stirrer was studied. At the short time DECOLORIZATION was complete and follows first order kinetic with respect of DYE concentration. The rate of DECOLORIZATION at the maximum absorption wavelength was monitored with spectrophotometric analysis. Effect of the important parameters such as initial concentration of H2O2, pH and initial concentration of DYE on the DYE DECOLORIZATION was studied. It was found that the rate of DECOLORIZATION increase with increase in H2O2 concentration up to 0.0294 mole.L-¹. The great rate of DECOLORIZATION observed at the pH=3. With increasing the initial concentration of the DYE up to 6.43×10-5 M, initial reaction rate was increased.
