杂多酸盐/聚苯胺/ZnO复合材料光催化降解龙胆紫

摘要

The SiW11Fe/PANI/ZnO was researched as the photocatalyst to degradation of the gentian violet.The influences of several operating parameters, such as initial dye concentration, pH, and the dosage of catalyst on the photocatalytic degradation of gentian violet were investigated.The degradation rate of gentian violet with SiW11Fe/PANI/ZnO was 93.03% after being treated for 120 min under 30 W ultraviolet light irradiation at pH 1, the initial concentration of gentian violet is 25 mg / L and the dosage of catalyst is 10 mg.%以SiW11Fe/PANI/ZnO为光催化剂.研究了龙胆紫溶液的起始浓度、溶液的起始pH值和催化剂的用量等不同条件对龙胆紫光催化降解效果的影响.结果表明,龙胆紫溶液光催化降解的最佳条件为染料的起始浓度为25mg/L,溶液的pH值为1,催化剂的用量为10 mg,30W紫外灯照射120 min,脱色率可达93.03%.
