| Abstract: | The Fe(Ⅲ)-doped TiO2 prepared via hydrothermal method is the anatase type by XRD characterizing,and the degeneration of Rhodamine B photocatalyzed by as-prepared Fe(Ⅲ)-doped A-TiO2 was studied.The results of photocatalysis show that the best degeneration rate of Rhodamine B is 76.5% under follow conditions: adding as-prepared 0.1650 g 5%(mole ratio) as-prepared Fe(Ⅲ)-doped A-TiO2into the 5 mg/L Rhodamine B solution which adjusted by nitric acid until its PH=5,then illuminated by Vis,stirring quickly at 43℃ for 6 h,and the best degeneration rate of Rhodamine B is 95.7% at the same condition but illuminated by UV(λ=254 nm). |
