| 摘 要： | 以新型载银TiO2为催化剂,太阳光为光源,对2,4-二氯苯酚水溶液进行了光降解。结果表明,载银TiO2催化剂的光解效率是单纯TiO2的1.9倍;经回归分析,由Langmiur-HinsheiWood方程计算出的反应速率R值与实验值的最大偏差不超过6.5%。证明该光解反应是非均相催化动力学反应。

| Abstract: | Solar photodegradation of 2,4-dichlorophenol in aqueous solution was studied using Ag-loaded titanium dioxide as catalyst.It has been shown that the catalytic activity of TiO 2 can be increased by loading silver.The kinetic property of the action fits Langmiur-Hinshel wood equation.The influence of parameters such as initial concentration and pH value of 2,4-dichlorophenol solution and the amount of catalyst and silver loaded was studied. |
