Activated carbon (AC) can catalyze hydrogen peroxide (H2O2) to generate hydroxyl radicals (· OH).The physical and chemical properties of AC are not only in favor of the reactant molecule diffusion and adsorption but also the catalytic oxidation reaction.The synergistic effect of AC's adsorption and catalysis enhance the ability of organic contaminants removal by AC-H2O2.The AC-H2 O2 system in removal of organic in wastewater was reviewed in detail.The effects of AC-H2 O2,AC-Fe2+-H2 O2 (-microwave/UV) and the system which AC is used as the heterogeneous Fenton catalyst support were analyzed,meanwhile,their reaction mechanisms were discussed.Moreover,some problems which exist presently were put forward,and the prospect of AC-H2O2 system was made.%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-H2 O2、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-H2 O2体系存在的问题及发展前景.
