【摘要】 对典型的含氮杂环有机物吲哚,采用阳极氧化和电芬顿法进行了降解研究.结果表明,吲哚在阳极氧化和电芬顿体系下可达到68%和97%的去除效果,而相应的TOC去除效果分别为15%和38%.通过盐桥将阴阳极室隔开后的处理结果表明,吲哚的主要降解途径为阳极氧化和羟基自由基氧化,依次经氧化吲哚和靛红后开环,部分吲哚在反应过程中聚合为二聚体.更多还原

【Abstract】 Using indole as a typical nitrogen-heterocyclic compound,the degradation was investigated by anodic oxidation and electro-Fenton.The removal of indole achieved 68 % and 97 % by anodic oxidation and electro-Fenton,respectively,while the decay of TOC was obtained as 15 % and 38 % correspondingly.Results of the degradation of indole in divided cells showed,the predominant degradation pathway by the electro-Fenton process was hydroxyl radical oxidation and anodic oxidation;indole was oxidized to oxindole and isatin and was ring opened,and indole was partly polymerized to dimer.更多还原
