| 摘 要： | 气体扩散电极（Gas Diffusion Electrode—GDE）作为阴极，通过氧气还原产生过氧化氢（H202），在亚铁离子催化剂存在的情况下形成Fenton试剂，从而间接氧化有机污染物，这方面的研究逐步引起人们的重视。本文综述了电极材料、电流密度、pH、催化剂等因素对处理效果的影响，提出了该方法存在的问题并对其发展趋势进行了展望。

| Abstract: | Hydrogen peroxide （H2O2） is generated by oxygen reduction at the Gas Diffusion Electrode （GDE） as the cathode. Reagent Fenton is formed with the existing ferrous ions as catalyst, and consequently organic pollutants are oxidized indirectly. Researches in this field are gradually attached importance. The treatment effect of factors such as electrode materials, current density, pH and catalyst were summarized in this paper. Some problems of this method were put forward and the development trend was prospected. |
