1.类Fenton技术

在研究

Fenton法中发现，除了

Fe2+能催化

H2O2分解产生出·OH外，其它的一些过渡金属离子如

Mn2+、Cu2+、Co2+等也可以加速或替代

Fe2+起到这种催化作用，从而实现氧化并去除有机污染物；金属离子促进

H2O2分解反应是因为产生了高活性的游离基。R&DdepartmentofYoujia1.类FR&DdepartmentofYoujia

1.电芬顿技术

电-Fenton方法是在常规

Fenton法的基础上引入了电化学方法，H2O2(溶解氧通过电化学的方法转化而来)与

Fe3+或

Fe2+(依靠电化学方法通过牺牲阳极所产生)构成了

Fenton试剂；或者外Fe3+/Fe2+及H2O2组成

Fenton体系，促使Fe2+和Fe3+形成良好的循环促使

H2O2转化为羟基自由基从而使废水中的有机污染物高效的氧化降解的方法R&DdepartmentofYoujia1.电芬R&DdepartmentofYoujia
