| 摘 要： | 文章为探究金属离子(亚铁离子、铁离子、二价铜离子、二价锰离子)对电化学氧化降解废水中4-CP的影响。采用自制的圆形电化学反应器,通过添加不同含量的金属离子来探究对4-CP去除效果的影响。试验的研究表明,亚铁离子具有较好的催化强化效果,平均催化效率可达24%,且Fe(Ⅱ)最适宜投加量为1.5mmol/L,催化效率可提高31.5%。另外其他三种金属离子均存在不同程度的抑制,其中抑制效果由强到弱为Mn(Ⅱ)>Fe(Ⅲ)>Cu(Ⅱ),且当Mn(Ⅱ)投加量为3.0 mmol/L时,完全抑制4-CP的电化学氧化降解。

| Abstract: | P-Chlorphenol was selected as a model pollution substrate.The influences of metal ions（ferrous ion,ferric ion,copper ion,and manganous ions） on its degradation were investigated in the wastewater by adding and changing the concentration of metal ions at ambient temperature and pressure.The results show that Fe（Ⅱ） ion can accelerate the degradation reaction,and improve the 4-CP removal rate.The Cu（Ⅱ）,Fe（Ⅲ）,Mn（Ⅱ） ions can hinder the degradation reaction and reduce the 4-CP removal rate.Especially when the concentration of Mn（Ⅱ） ion was 3.0mmol/L,the degradation of 4-CP by electrochemical oxidation was completely restrained. |
