摘　　要：用溶胶凝胶法制备了CaTiO_(3),研究了CaTiO_(3)粉体对亚甲基蓝溶液的降解性能,及CaTiO_(3)投加量、亚甲基蓝初始浓度、pH值、淬灭剂对光催化效果的影响,并从动力学角度分析其原因.结果表明,在12 W汞灯作用下,经120 min,0.1 g CaTiO_(3)对10 mg/L亚甲基蓝溶液降解率达80%以上.CaTiO_(3)is prepared by sol-gel method and the degradation performance of CaTiO_(3)powder on methylene blue solution is studied.The effects of CaTiO_(3)dosage,initial concentration of methylene blue,solution pH,and quencher on the photocatalytic effect are studied,and results are analyzed in terms of dynamics.Results show that under the illumination of a 12 W mercury lamp,the degradation rate of 0.1 g CaTiO_(3)to 10 mg/L methylene blue solution is more than 80%after 120 minutes.
