| 摘 要： | 本研究以高压汞灯为光源，系统地研究了１６种偶氮染料在水溶液中的ＴｉＯ２光催化降解。结果表明，这些偶氮染料的光解为一级动力学反应，采用ＴｉＯ２光催化降解方法处理所研究的偶氮染料是可行的，并初步探讨了染料的结构与光解反应表观速率常数之间的关系。

| Abstract: | Photocatalytic degradation of 16 azo-dyes in TiO2 suspension and irradiated by a high pressure mercury lamp has been studied. The results show that the use of photocatalytic reaction to treat wastewater containing azo-dyes is feasible, and the photocalytic reaction of each azo-dye follows pseudo-first-order kinetics. The initial qualitative relationships between molecular structure and the determined pseudo-first-order photocatalytic degradation rate constants for the azo-dyes under study are discussed. |
