摘　　要：通过测定Fenton试剂氧化作用对含芳香硝基化合物水样氧COD的影响,研究了Fenton试剂对芳香硝基化合物适宜的氧化条件,比较Fenton试剂对各类芳香硝基化合物的氧化能力。主要研究对象有硝基苯、对硝基苯酚、对硝基氯苯。经研究表明,利用Fenton试剂能有效氧化芳香硝基化合物,COD去除率均在60%以上。Fenton试剂氧化芳香硝基化合物能力从大到小的顺序依次为:对硝基苯酚、硝基苯、对硝基氯苯。Through the tests of the effects of Fenton reagent oxidation on COD of aromatic nitro compound solutions,and the optimum conditions for the oxidation of aromatic nitro compounds by Fenton reagent was studied,and COD in aromatic nitro compounds solutions before and after oxidation was compared. The test chemicals of study were nitrobenzene,nitrophenol,nitro chlorobenzene. The results showed that Fenton reagent could be used to effectively oxidize aromatic nitro compounds and COD removal rate reached more than 60%. The capacity of Fenton reagent to oxidize aromatic nitro compounds was arranged in a sequence from large to small： nitrophenol,nitrobenzene,nitro chlorobenzene.
