| 摘 要： | 为了考察物质结构对难生物降解芳香化合物电催化氧化的影响,实验研究了典型的酚类和胺类芳香污染物的电化学氧化降解。结果表明:电催化氧化技术可有效处理水中的芳香化合物,苯环上取代基对有机物的电催化降解活性有很大影响,带有供电子取代基团的芳香化合物的电催化降解速率比带有吸电子取代基团的芳香化合物的电催化降解速率快。处理2 h,苯酚、苯胺和甲苯胺接近完全去除,对氯苯酚和对氯苯胺的去除率超过90%,对硝基苯酚和2,4-二氯酚的去除率也达到70%左右。

| Abstract: | In order to research the effects of structure on electrochemical oxidation of biorefractory aromatic compounds,electrocatalytic degradation of phenols and amines was studied in this paper.Results showed the efficiency on treatment of the aromatic compounds by electrochemical oxidation was obvious.The ring substituents influenced the electrocatalytic reactivity of the aromatic compounds significantly,the relationship between structure and electrocatalytic reactivity was interrupted by Hammett constant.The el... |
