摘要
活性炭(AC)优良的物化性质不仅利于反应物分子的扩散与吸附,还利于过氧化氢(H2O2)催化分解产生羟基自由基(·OH),进而促进氧化反应的进行,在AC-H2O2体系中,二者甚至可以产生协同效应,增强难降解有机污染物的去除功效。综述了AC催化H2O2处理水中有机污染物的研究进展,分析了AC-H2O2、AC-Fe2+-H2O2(-微波/UV),以及AC作为载体的非均相Fenton催化剂体系影响因素,探讨了它们的反应机制,并总结与展望了AC-H2O2体系存在的问题及发展前景。
Activated carbon （AC） can catalyze hydrogen peroxide （H202） to generate hydroxyl radicals （ OH）. The physical and chemical properties of AC are not only in favor of the reactant molecule diffusion and ad- sorption but also the catalytic oxidation reaction. The synergistic effect of AC＇s adsorption and catalysis enhance the ability of organic contaminants removal by AC-H2 02. The AC-H2 02 system in removal of organic in wastewater was reviewed in detail. The effects of AC-H202, AC-FeE＋-HzO2 （-microwave/UV） and the system which AC is used as the heterogeneous Fenton catalyst support were analyzed, meanwhile, their reaction mechanisms were discussed. Moreo- ver, some problems which exist presently were put forward, and the prospect of AC-H202 system was made.
