摘　　要：利用掺银负载型TiO2作为光催化剂,对氯苯溶液进行紫外光催化降解处理。研究表明,氯苯光催化降解属表观一级动力学过程,可以用Langmuir-Hinshelwood模型来描述,并得到动力学方程。A photocatalysis degradation(PCD) of chlorobenzene in aqueous solution has been studied by using titanium dioxide(TiO2) type of catalyst with Ag element. Kinetics research shows that the photocatalytic degradation reaction can be expressed by an appearance first order equation under the certain concentration chlorobenzene in water, which also can be described by Langmuir- Hinshelwood Model.
