| 摘 要： | 提出使用将ＴｉＯ２固定于玻璃螺旋管内壁的光降解装置，水溶液中苯酚及对氯苯酚可迅速降解并遵守动力学一级反应。向溶液中增加Ｏ２、或加入Ｈ２Ｏ２和少量铜离子可提高两者的光降解效率。指出：Ｃｌ－不利于两者的降解，苯酚和对氯苯酚的降解最佳ＰＨ分别在４．５和５左右，降解时间约为１ｈ。

| Abstract: | The degradation of phenol and 4-chlorophenol under TiO2 photocatalysis is rapid and follows the first order kenitic reaction. Oxygen and hydrogen peroxide can promote the reaction. A small amount of copper ion accelerates the reaction. On the other hand, addition of Cl- hinders the degradation. The optimum PH for the degradation of phenol and 4-chlorophenol are 4. 5 and 5 respectively. The total degradation needs about 1 hour. |
