| 摘 要： | 以紫外灯为光湖，在圆柱型光反应器中，负载在镍网上的ＴｉＯ２为催化剂，研究了水中苯胺光催化剂降解行为，结果表明苯胺的降解动力学可用Ｌａｎｇｍｕｉｒ－Ｈｉｎｓｈｅｌｗｏｏｄ方程来描述，对苯胺的浓度、介质ｐＨ、液体流速、氧气浓度和外加Ｈ２Ｏ２等因素对光催化反应的影响进行了研究，并以实验现象予以解释。

| Abstract: | The photocatalytic degradation of aniline in water was studied in annular photoreactor with UV lamp as light source and titanium dioxide immobilized on porous nickel as catalysts. The results showed that the kinetic of photocatalytic degradation rate of aniline can be described by Langmuir Hinshelwood equation. The effects of the concentration of aniline, pH, flow rate, concentration of oxygen and external addition of H\-2O\-2 were also investigated and the results were explained. |
