摘要

本文选择了以Ｎ，Ｎ′－二（１－甲基庚基）乙酰胺（简称Ｎ５０３）从盐酸溶液中萃取硒（Ⅳ）的最佳萃取及反萃条件，发现硒大部分以物理分配形式被萃取，而仅有２３％～２７％的硒以化学形式被萃取．经两次萃取，萃取率达１００％．这项研究将为铜厂从阳级泥中提取硒提供了一条新途径

Abstract

The extraction and back extraction conditions of Se(Ⅳ) with N503 have been researched and it comes to the conclution that there exist two kind of extraction of Se(Ⅳ) physical process and chemical process. The extraction efficiency of Se(Ⅳ) is proved to be one hundred percents by two times of extraction.
