摘要：
In order to improve oxidation efficiency of Fenton reaction, heteropoly acid was chosen as activator. A new photocatalysis system was established. In photochemical reactor, uv lamp was used as light sources, phosphotungstic acid as photocatalysis additives, UV/Fenton/heteropoly acid system effect to photocatalysis degradation on eosin Y simulative dyeing was studied. Heteropoly acid photocatalysis degradation mechanism to dye, factors that could affect photocatalysis degradation rate of dye, ways to improve photocatalysis degradation efficiency to dye were preliminary studied. Experiments results showed that: H2O2 addition amount to the solution, Fe2+ concentration, pH value of the solution could affect photocatalysis degradation result. From the experiments, optimum reaction conditions were: pH value was 5 similar to 6, 30%H2O2 addition amount was 2mL, FeSO4 dose was 0.02 g/L.
