| Abstract: | 采用溶胶-凝胶法制备了La2O3/ZnO/TiO2复合光催化剂,以紫外灯为光源,活性艳红K-2BP为模型降解物,研究了La2O3/ZnO/TiO2的光催化性能。结果表明:当锌和镧的掺杂量w(ZnO)=20%,w(La2O3)=0.5%,煅烧温度为500℃时,La2O3/ZnO/TiO2复合光催化剂的光催化活性最高;当催化剂投加量4 g/L,通气量800 mL/min,初始pH值3.12时,La2O3/ZnO/TiO2对活性艳红K-2BP的降解效果最好。实验证明,La2O3/ZnO/TiO2对活性艳红K-2BP的降解遵从Lang-muir-Hinshelwood动力学模型,测得其反应速率常数k=11.5 mg/(L.min);吸附常数K=2.88×10-2L/mg。 |
