| Abstract: | Copper ion doped TiO2/bentonite composite photocatalyst was prepared by sol - gel method with bentonite as carrier, butyl titanate and copper nitrate as raw materials. The wastewater of direct sky＇ - blue＇ 5B dye was treated by the photocatalyst. The results showed that the decolorizing rate of direct sky＇-blue＇ 5B dye solution（50 mg/L）was93.5% under the conditions of visible light irradiation 120 min, mass fraction of copper ion doped 1.0% ,calcination temperature 500 ℃ , pH value of wastewater 3, content of catalyst 5 g/L. |
