有机污染物苯胺在催化电极上氧化降解的途径

采用循环伏安法和测定催化电极在不同介质中的阳极极化曲线得到析氧电位的方法,考察了有机污染物苯胺在催化电极上的电催化氧化行为.研究结果表明,苯胺在不同催化电极和反应介质中的电催化氧化降解途径可分为协同氧化降解和间接氧化降解2种模型.催化电极对有机污染物的电催化性能、电极的析氧电位大小以及处理体系的介质环境等多方面因素决定了电催化氧化的降解途径并将影响电化学降解的效率. 

The Ways of Oxidative Degradation of Organic Pollutant Aniline on Catalytic Electrods

The electrochemical oxidation reaction of organic pollutant aniline on catalytic electrodes is studied through cyclic voltammetry and anodic polarization curves of the catalytic electrodes measured in different intermedia.The results showed that there were two degradation ways of electrocatalytic oxidation of aniline in different electrodes and variant reaction intermedia,which are co\|oxidation and indirect oxidation.The degradation process and efficiency are influenced by factors such as the intermedia of the solution,the electrocatalytic activities and oxygen evolution voltage of the electrode.
