- 摘要：:以紫外灯为光源, 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降解行为.结果表明苯胺的降解动力学可用LangmuirHinshelwood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, 并对实验现象予以解释.
- 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 H2O2 were also investigated and the results were explained.
