摘要
用自制的Si W11Cr/PANI为光催化剂,以龙胆紫溶液模拟工业染料废水,研究了Si W11Cr/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p H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,p H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 Si W11 Cr / PANI were studied. The effects of the initial concentration of the gentian violet in the catalyst quantity and the solution p H on decolorizing efficiency of the solution were discussed in detail. The degradation rate of gentian violet in with Si W11 Cr / PANI was 97. 97% after being treated for 170 min under the UV light irradiation at p H 3,using 15 mg / L.
