摘　　要：采用芬顿法对硫酸锰溶液中残余有机物进行氧化脱除,通过测定溶液COD值的变化来判断脱除效果。考察了溶液的初始pH、Fe2+浓度、H2O2/Fe2+摩尔比、反应时间、反应温度等对COD脱除率的影响。结果表明,在初始pH为3.50、Fe2+浓度0.03 mol/L、H2O2/Fe2+=5、30℃反应60 min时,溶液COD脱除率为75.35%Fenton reagent was introduced to remove residual organics in manganese electrochemical solution by oxidation treatment,and variations of COD values of solution were measured to evaluate the removal effects.The effects of initial pH value,ferrous ions concentration,H2O2/Fe2＋molar ratio,reaction time and temperature on COD removal rate were investigated.The results show that COD removal rate is75.35% under the conditions including initial pH value of 3.50,ferrous ions concentration of 0.03mol/L,H2O2/Fe2＋molar ratio of 5,reaction temperature of 30 ℃,and reaction time of 60 min.
