摘　　要：以TiO2 粉末为原料 ,采用偶联剂法在聚丙烯多面球表面涂敷TiO2 ,80℃干燥 2h ,制成负载型TiO2 光催化剂 .以阳离子金黄为研究对象 ,紫外灯为光源 ,研究溶液初始浓度、溶液 pH值、曝气、乙醇用量、H2 O2Using adhesive, TiO 2 power was immobilized on the multi-sided balls made of polypropylene and then dried at 80℃.With UV lamp as light source and titanic oxide on the multi-sided balls, the photocatalytic degradation of positive ion golden yellow in water was studied. The effects of concentration of liquor, pH value, the amount of ethanol and H 2O 2 were also studied.
