摘要:  以可溶性铁为阳极,多孔石墨电极为阴极,Na2SO4为支持电解质.通电后,铁从阳极溶解生成二价亚铁离子Fe2+,氧在阴极上还原为过氧化氢H2O2,于电解现场发生Fenton反应,产生羟基自由基即Fenton试剂.在低电流密度(10mA/cm2)下,可有效地抑制阴、阳两极副反应的发生,所产生的羟基自由基浓度足以有效地进行染料废水的降解与脱色,脱色率达100%,CODcr去除率达80%.

关键词: 染料, 降解, 脱色, 羟基自由基, 电化学方法

Abstract: The electro_chemical processing to produce Fenton reagent has been described.Fenton reagent having a high redox potential has been used as an oxidant in treatment of dye wastewater.Results show that both of the degradation and decolourization of dyes are efficient.The decolourization of dye wastewater reaches 100%.The COD removing rate is about 80%.
