硅钨酸盐/聚苯胺材料光催化降解龙胆紫

摘要

用自制的SiW11 Cr/PANI为光催化剂,以龙胆紫溶液模拟工业染料废水,研究了SiW11 Cr/PANI的光催化降解性能,实验主要考察了催化剂的用量、染料溶液的初始浓度、染料溶液的pH等对龙胆紫溶液脱色率的影响。实验表明,光催化降龙胆紫的最佳条件是：催化剂用量3 mg, pH 值为3,染料溶液初始浓度为15 mg/L,紫外灯光照170 min,脱色率为97.97％。%The gentian violet solution was used as simusated dye wastewater and the photocatalytic activity of materials SiW11 Cr/PANI were studied. The effects of the initial concentration of the gentian violet in the catalyst quantity and the solution pH on decolorizing efficiency of the solution were discussed in detail. The degradation rate of gentian violet in with SiW11 Cr/PANI was 97. 97% after being treated for 170 min under the UV light irradiation at pH 3, using 15 mg/L.
