摘要
选用20％三烷基胺+80％加氢煤油作为萃取剂,进行四级萃取实验,探讨络合萃取技术处理苯胺-硝基苯 废水工业化的可能性。实验结果表明,采用三烷基胺-加氢煤油混合溶剂对苯胺-硝基苯废水进行萃取,具有相当高 的COD去除率。
20% trialkyl amine + 80% hydrogenating kerosene was chosen as extractant to carry out 4-stages extraction test and the industrialization possibility of aniline-nitrobenzene treatment by complexation extraction was explored. The test results showed that very high COD removal rate could be obtained by employing trialkyl amine -hydrogenating kerosene mixed extractant to extract aniline -nitrobenzene wastewater.
