摘　　要：用三辛胺萃取法处理高浓度含Ｃｒ（Ⅵ）废水褚莹，刘沛妍，阎淑荣，吴子生，严忠（东北师范大学化学系长春１３００２４）关键词三辛胺，Ｃｒ（Ⅵ），萃取处理含Ｃｒ（Ⅵ）废水的萃取剂有三烷基胺（Ｎ２３５）、三辛胺（ＴＯＡ）、季胺盐及磷酸三丁脂（ＴＢＰ），稀释剂为...A noval extraction system was introduced using trioctylamine as extractant and xylene or kerosene as diluent. This system exhibited high oxidation resistance without interfacial emulsification, therefore, the so-called third phase was not produced in the extraction process. Various factors influencing the extraction effectiveness were discussed. The experimental results of Cr(Ⅵ) recovery from waste water of high concentration Cr(Ⅵ) were reported.
