摘　　要：电芬顿法作为一种新型电化学氧化技术,因其强氧化能力以及环境友好的特性引起了国内外的广泛关注。电芬顿反应通过电极产生H2O2和(或)Fe2+,进行一系列反应生成具有强氧化能力的羟基自由基·OH。为了提高电子传递速度,产生更多芬顿试剂,国内外学者研发出不同类型的电芬顿反应器。通过分析电芬顿反应中·OH浓度与有机物浓度间的关系,大多数学者在准一级反应动力学基础上确定了反应常数,然而,目前其应用仍只停留在实验室阶段,电芬顿技术的效率及机理仍需要进一步研究改进。As a novel electrochemical oxidation process,Electro-Fenton has attracted great attention at home and abroad since its strong oxidbillity and environmental friendliness.Electro-Fenton process generates H2O2 and （or）Fe2 ＋ on the surface of electrodes and creates · OH,a strong oxidizer,through a serious of reactions.Many scholars determined the reaction constant on the basis of pseudo-first order reaction kinetics by analyzing the relationship between the concentration of · OH and the concentration of organic pollutants.However,the applications of Electro-Fenton reaction kinetics was still in laboratory scale,the reaction mechanism and efficiency of Electro-Fenton process still needed to be further studied and promoted.
