| 摘要: |
| 为强化多相类芬顿反应的速率,采用可见光辅助树脂载铁(FeIII/R)为催化剂催化过氧化氢降解水中孔雀石绿(MG).结果表明,可见光能强化MG的降解.探讨初始pH值、过氧化氢初始浓度和MG初始浓度及叔丁醇等对反应速率的影响.叔丁醇实验表明羟基自由基和高价态铁在反应中同时存在.催化剂重复使用表明铁在树脂表面负载比较牢固,具有较好的稳定性. |

| Abstract: |
| In order to increase the reaction rate of the heterogeneous Fenton-like,the catalyst FeIII /R was used to catalytically decompose H2O2 under visible light for the removal of Malachite Green (MG) in aqueous solution.The effect of initial pH,initial H2O2 concentration,initial MG concentration and t-butanol on the reaction rate was also discussed.The result shows that the visible light can enhance the degradation of MG.The experiment of t-butanol shows that the ferryl iron and hydroxyl radical coexist in the system.Repeated use of catalyst does not decrease the removal rate of MG. |
| Key words: heterogeneous Fenton-like Malachite Green hydroxyl radical ferryl iron ion exchange resin |
