摘要
以聚乙烯吡咯烷酮(PVP)为稳定剂,采用化学沉积法制备了磷酸银/树脂复合物,降解亚甲基蓝,研究其光催化活性,并对样品进行了XRD和SEM表征。探讨了不同的光源、催化剂投加量、PVP含量、p H值等因素对亚甲基蓝降解率的影响。结果表明,在太阳光(夏天早上9点到11点的阳光)下,偏酸介质中,催化剂用量为0.8 g/L,PVP质量分数为0.01%的磷酸银/树脂复合物,液面高度为15 cm的条件下对亚甲基蓝有最佳降解效果。
Silver phosphate/resin composite is prepared by a chemical deposition method with polyvinylpyrrolidone（PVP）as stabilizer ,to degrade methylene-blue ,the photocatalytic activity is studied and also the sample is characterized by means of XRD and SEM .The influences of the light source ,catalyst amount ,PVP content ,pH on the degradation are investigated in details .The results show that the effect of methylene-blue degradation is best in partial acid medium and sunlight from 9 am to 11 am in summer when catalyst amount is 0 .8 g/L ,0 .01% PVP/silver phosphate/resin composite is contained and the depth of the solution is 15 cm .
