| 摘 要： | 研究了１３种苯甲酸类化合物在固定膜平板型反应器中的光催化降解。首先用紫外辐射法将粉末二氧化钛固定在平板上；并研究了苯甲酸化合物在此平板上的光催化降解，考察了固定催伦剂下污染物的降解动力学，以及不同取代基团和取代位置对光降解速率的定性影响；最后探讨了苯甲酸物质光降解速率与其结构的定量关系。

| Abstract: | Study on the photocatalytic degradation of 13 kinds of benzoic acids in the fixed film flat-plate reactor have been conducted. Firstly, Degussa P25 TiO2 powder was deposited on the flat-plate under ultraviolet radiation, then the degradation of benzoic acids on this plate were studied, including degradation kinetics of the contaminants in the fixed catalyst system and influence of different constituents and different positions on the degradation rate. Finally, the relationship between photocatalytic degradation rate and its structure, i.e. QSAR was discussed. |
