摘　　要：UV/Fenton Catalyst system was used to treat Eosin B in simulated dye wastewater developed here.Studies showed that when the initial concentration was 50mg/L,at 25℃,the best condition was that pH=4.5 =0.54mol/L /≈1/29(Mol ratio) t=100min.Under this optimized condition,the decolorization rate was 99.7% above.The initial concentration of Eosin B and different effect of cation and anion on its decolorization were studied.Finally,comparing before and after UV spectrum,the results showed that the degradation of Eosin B was completed.UV/Fenton Catalyst system was used to treat Eosin B in simulated dye wastewater developed here. Studies showed that when the initial concentration was 50mg/L, at 25℃ ,the best condition was that pH = 4.5 [ Fe^2＋ ] = 0. 54mol/L [ Fe^2＋ ]/[ H2O2 ] 1/29 （Mol ratio ） t = 100min. Under this optimized condition, the decolorization rate was 99. 7% above. The initial concentration of Eosin B and different effect of cation and anion on its decolorization were studied. Finally, comparing before and after UV spectrum, the resuhs showed that the degradation of Eosin B was completed.
