摘　　要：用Fenton试剂—超声波振荡法对硝基苯水溶液进行降解处理,采用气相色谱-质谱联用法分析降解的中间产物,用离子色谱法分析降解的最终产物。实验结果表明:硝基苯降解中间产物中含有间二硝基苯,邻、间、对硝基苯酚及苯酚;降解的最终产物主要为硝酸根,本文同时研究了中间产物在降解过程中浓度的变化规律。<Abstrcat>Nitrobenzene dissolved in water was degraded by Fenton reagent-ultrasonic wave. The intermediate products of (degradation) were determined by gas chromatography-mass spectrometry. The final products were determined by ion chromatography. The results showed that the degraded intermediate products of nitrobenzene contained 1,3-dinitro-benzene, 0,m,p-nitrophenol, (phenol.) The final products most were nitrate. The dependence of concentration of intermediate products on ultrasonic treatment time was studied.
