| 摘 要： | 采用硬脂酸溶胶凝胶法合成出钙钛矿型复合氧化物LaCoO3,并以其为催化剂对染料酸性红B进行降解实验.以高压汞灯为光源,研究了催化时间、催化剂用量、起始浓度以及溶液pH值对降解率的影响.在优化条件下,100mL、10mg/L酸性红B溶液用0.25g催化剂降解2h,降解率达到88.70%.

| Abstract: | Perovskite oxides LaCoO3 as a photo catalyst was prepared by stearic acid sol-gel used in the degradation of acid red B with a luminous Hg lamp as irradiator.The influences of reaction time,amount of catalyst,initial concentration of acid red B and pH of solution were investigated.The degradation rate of acid red B was up to 88.7% with 0.25g catalyst in 100mL,10mg/L acid red B degradation 2h. |
