摘　　要：Three types of simulated commercial reactive dye wastewater, separately prepared with FN-2BL red, C-R blue and C-2R yellow, were oxidized with UV/ferrioxalate/H2O2 system, especially by the introduction of Fe2+ ion. The experimental results show that the optimized experimental conditions are pH=3.5, [Fe2+]=1mM, H2O2782mg/L for FN-2BL red and C-R blue and H2O2646mg/L for C-2R yellow, t=4h and T=80℃ when the concentration of dye is 400mg/L. Under such conditions, the observed COD and color removal efficiencies are above 94% and 99%, respectively for all the cases. This investigation has provided fundamental information for the treatment of wastewater containing reactive dyes using UV/ferrioxalate/H2O2.
