摘要
利用废铁屑对硝基苯废水进行预处理,可以使废水中的硝基苯转化为苯胺,然后在废水中加人H2O2,使H2O2与废水中的Fe2+构成Fenton试剂,反应生产OH.自由基,OH.自由基具有强烈的氧化性,将苯胺和硝基苯中的苯环打开,形成断链,再进一步将其矿化分解。
Nitrobenzene wastewater was pretreated by an iron scrap process, which resuhed in the conversion of nitrobenzene to aniline. Fenton reagent oxidation process for nitrobenzene and aniline degradation was investigated by using Fe2＋ as catalyst and H2O2 as oxidant. The benzene ring in the nitrobenzene to aniline was oxidized and decomposed by OH· .
