摘要
采用30 W石英紫外灯作为光源,研究了乐果在二氧化钛悬浮体系中光催化降解反应的动力学规律。考察了乐果起始浓度、TiO2用量、溶液pH值及温度对乐果光催化降解速率的影响,结果表明,乐果光催化降解符合表观零级动力学规律。由于速率常数k与乐果起始浓度有关,表明乐果光催化降解反应不是一个简单的零级反应。
The photocatalytic kinetics of Rogor in aqueous TiO2 dispersions under radiation with 30W UV lamp were investigated. It was shown that the kinetics for photocatalytic degradation of Rogor follwed zero order kinetic law, and the initial concentration of Rogor,consumption of TiO2, pH value and temperature affected the degradation rates. The photoeatalytie degradation of Rogor was not a simple zero order reaction, because the rate constants was related to the initial concentration of Rogor.
