中文摘要：
对臭氧单独氧化和臭氧催化氧化下的苯胺降解效率进行了比较，并通过液质联机分析了氧化过程中产物变化情况。实验结果表明，催化剂MnO2-CuO—CeO2／沸石的添加能有效地提高臭氧氧化苯胺的降解率，当苯胺初始浓度为200mg／L，反应20min后，苯胺的去除率由原来的75％提高到89％；通过LC—MS分析，臭氧催化氧化苯胺降解过程中代谢产物依次为对亚胺醌、对苯醌、马来酸和草酸，并由此推断出了臭氧催化氧化降解苯胺的途径。
英文摘要：
We compared the degradation efficiency of aniline by ozonation alone and catalyzed ozonation, and ananylzed the change of products in oxidation process by LC-MS. The results showed that MnO2-CuO-CeO2/ zeolite catalyst could effectively improve the degradation rate of aniline by ozonation, and when original aniline concentration was 200 mg/L, the removal efficiency of aniline increased from 75% to 89% after 20 rain; LC-MS analysis showed that the degradation products of aniline by catalyzed ozonation are successively p-benzoquinoni- mine, p-benzoquinone, maleic acid and oxalic acid ; and according to that, the degradation pathway of aniline by ozonation is inferred.
