| 摘 要： | 研究了以５００Ｗ直管高压汞灯为光源，在双氧水和亚铁离子的体系中，对硝基苯进行光降解的可能性。结果表明，在实验条件下，本系统对硝基苯有明显的降解效果。浓度为５０ｍｇ／Ｌ的硝基苯经过６０ｍｉｎ的光照，其降解率可达９１．７％。此外，还探讨 铁离子浓度、双氧水浓度、硝基苯浓度、ｐＨ值等因素对光降解的影响。

| Abstract: | The photodegradation of Aqueous Nitrobenzene was studied.The catalyst was the system of UVhydrogen peroxide and ferrous ions.It showed that nitrobenzene was remarkablely decomposed under the condition of the experiment.The initial concentration of 50mg/L nitrobenznce solution decayed to 4.15mg/L in about 60 min of UV irradiation.The influence of parameters such as initial concentrations of H2O2 and Fe2+ and pH of the sample was studied. |
