摘　　要：UV-vis/草酸铁络合物/H2O2法是一种高级氧化工艺,这个工艺产生的羟自由基·OH是一种很强的氧化剂,能很快和水中有机物发生反应.以联苯胺、邻联甲苯胺、邻甲苯胺、3,3-二甲氧基联苯胺和对苯二胺为处理对象,对UV-vis/草酸铁络合物/H2O2法的氧化能力和效果进行了全面系统试验研究,并确定了UV-vis/草酸铁络合物/H2O2法降解苯胺类化合物的最佳工艺条件为:pH=3.0～4.0;Fe2+∶H2O2∶C2O42-=1∶4～5∶10～12(mmol/L).结果表明:UV-vis/草酸铁络合物/H2O2法处理高浓度苯胺类化合物废水是非常有效的,16min内苯胺类化合物去除率均在95%以上.The UV-vis/H 2 O 2 /Ferrioxalate advanced oxidation process is one of photo degradation methods of or-ganics.The hydroxyl radical(·OH)generates in the process,which is a strong oxidant and reacts rapidly with or-ganic compounds in wastewater.The oxidation behavior of Benzedrine?O-toluidin?O-tilidine?P-pheylenedia-nimine?3,3-dimethoxybenzidine treated by this oxidant was researched.The optimum technology conditions of the UV-vis/H 2 O 2 /Ferrioxalate process to remove anilines from water were determined:pH=3.0～4.0?Fe 2+ ∶H 2 O 2 ∶C 2 O 42- =1∶4～5∶10～12(mol/L).UV-vis/H 2 O 2 /Ferrioxalate process is very efficient and useful for the treatment of water highly contaminated by aniline and the removing efficiency of anilines was more than95%within16min.
