摘要

In this study, the photo-Fenton process was used to identify degradation conditions of Reactive Blue 19~ (RB19) and Reactive Red 21 ~(RR21). The effects of pH, initial H_2O_2 and FeSO4 concentrations, time, and UV light intensity in determining the degradation rate were studied. The optimal conditions for the degradation of 0.156mmol L_1 RB19 and 0.036mmol L_1 RR21 in water were found to be: pH 4, 0.1mL 30% H_2O_2 for RB19 and RR21, 0.2mL 0.5% FeSO_4 for RB19 and 0.1mL 0.5% FeSO_4 for RR21, 20mL volume, and a temperature of 20°C. Optimal conditions were applied to synthetic dye wastewater using small amounts of H_2O_2 in 1 L for degradation. The degree of degradation efficiency of synthetic wastewater by the photo-Fenton process was found to be >95% within 10 min.
