摘　　要：研究了溶胶—凝胶法制备以活性炭为载体的TiO2膜。通过实验确定了溶胶—凝胶体系的最佳组成,对涂膜的次数、煅烧温度、保温时间等因素进行实验,确定了涂膜的最佳工艺,并用于处理有机染料污水,脱色率达92%。Preparing TiO_2 membrance by sol-gel method,is studied in this article, which makes active carbon as carrior. The optimal composing of Sol-gel system, daubing times, calcining heat and heat preservation time are experimented in order to confirm optimal technics for dealing with organic dyestuff sewage. Decoloration rate reach 92%.
