摘要
以钛基二氧化铅电极作为阳极,铅电极为阴极,对含对氯苯酚的模拟废水进行了电解氧化处理,考察了初始浓度、电流密度、pH、电解质浓度等对化学需氧量去除率的影响。结果表明,在对氯苯酚的初始浓度为8mmol/L、电流密度10A/dm2、pH=11、支持电解质0.5mol/L Na2SO4的条件下,6h降解后化学需氧量去除率达到65.3%。
The 4-CP was electrolytically oxidated by using Pb cathode and Ti/PbO2 anode. And the effects of initial concentration, current density, pH and concentration on the COD removal rate were also exam- ined. The results show that COD removal efficiency can reach to 65.3% under the best conditions of ini- tial concentration 8mmol/L, current density 10A/dm2, pH value 11, concentration of electrolyte 0.5 tool/Land time 6 h.
