| 摘 要： | 选取一组芳香族化合物作为研究对象，以ＴｉＯ２为催化剂、高压汞灯照射研究其在水溶液中的光催化降解情况，以半衰期ｔ１／２表示化合物的光催化降解性能。利用正辛醇／水分配系数ｌｏｇｋｏｗ和分子连接性指数对该类化合物进行相关性分析，建立定量结构－光催化降解性能关系模型。结果表明：分子连接性指数１Ｘｖ，２Ｘｖ，３Ｘｖｐ和（３Ｘｖｐ＋３Ｘｖｃ）与半衰期ｔ１／２有较好的相关性。

| Abstract: | Photocatalytic oxidation of aromatic compounds in aquous suspension was studied with UV illumintated titanium dioxide powder in this paper.The half lives of photocatalytic degradation were determinded and molecular connectivity indexes and n octanol/water partition coefficients of this compounds were calculated.The quantitative structure photocatalytic degredation activity relationship model was obtained by using linear regression program.The results showed that the photocatalytic degredation of compounds could be described better by their molecular connectivity indexes (e.g. 1 X v, 2 X v, 3 X v p,( 3 X v p 3 X v c). |
