| 摘 要： | 用二氧化氯氧化降解８种苯胺类化合物，测定了ＣＯＤ去除率与时间及ＣＯＤ去除率与ＣｌＯ２用量之间的关系；结果表明最终的ＣＯＤ去除率多数都在７０％以上，羟基类苯胺化合物可达９０％以上．反应符合ｌｎＣＯＤ＝Ｋ１ＷＣｌＯ２＋Ａ１及ｌｎＣＯＤｔ＝Ｋ２ｔ＋Ａ关系式．ＣＯＤ去除率还与ｐＨ值的大小有一定的相关性．

| Abstract: | The COD removal efficiency in aromatic amine compounds was 70%-90%.During the treating process,the relationship between the change of COD, the amount Of ClO2 and time was in accord with the following equations:InCOD =InCOD0-k' ClO2] CODt=COD0e-kt(k,k' was constant)Substitute groups had effect on the final COD removal efficiency. The ranking of final COD removal efficiency (highest to lowest)was:(o, m, p)hydroxy aniline>p-methyl oxyaniline > aniline > p-nitroaniline>o- nitroaniling> p-chloroaniline. PH also affected the oxidizing efficiency of ClO2.The effects de peneded on the kinds of aromatic amine compounds. |
