摘　　要：采用正交实验设计研究了用脂肪酸甲酯处理工业苯胺废水的条件。实验表明:在影响苯胺废水萃取效果的诸因素中,影响大小的顺序为pH值、油水相比、溶液初始浓度和温度。在pH值=7,油水相比为2∶1,20℃的最佳萃取条件下,高浓度苯胺废水经萃取剂脂肪酸甲酯三级萃取后,苯胺去除率达99.98%。The condition of extracted aniline in the water with fatty acid methyl esters （FAMEs） was studied. The result showed that the order of the influence as followed ： pH 〉 the ratio of solvent to wastewater 〉 preliminary content 〉 temperature. In the best condition of pH = 7.0, 20 ℃, S/F = 2/1, the removal ratio of aniline in the wastewater was 99.98% after the high content of aniline wastewater was extracted three times with FAMEs.
