The photocatalytic degradation of atrazine and PCP, a endocrine disruptors, has been investigated over TiO2 photocatalysts under ultraviolet (UV) light irradiation. The effect of operational parameters, i.e., pH, light intensity and persulphate concentration on the degradation rate of aqueous solution of atrazine and PCP has been examined. The results presented in this work demonstrate that, as pH and the light intensity increased, the photocatalytic reaction rates were enhanced. Individual use of TiO2-persulphate was far more effective than using only TiO2 in atrazine and PCP removal. Based on the overall experimental results, the photocatalytic oxidation of atrazine and PCP with the coated TiO2 photocatalyst is found to be very effective under the operational conditions delineated in this study.
