前言 文献[1]报道,萃淋树脂是一种含萃取剂的树脂,一般是以苯乙烯-二乙烯苯为骨架,基本上是大孔结构和含有一种选择性萃取剂的共聚物的总称。其外观与一般园球状的离子交换树脂相同,其中的活性组分为萃取剂。因此它具有离子交换树脂和萃取剂两者之优点,具有水力学性能好,萃取剂流失少、使用寿命长(比采用一般担体的萃取色层法含萃取剂量要高)、装柱简单、流速快等优点。本文就HDEHP萃淋树脂对钇的分离作了一些探讨,并成功地运
Preface [1] reported that the extraction of resin is an extractant-containing resin, usually based on styrene - divinylbenzene skeleton, is basically a macroporous structure and copolymer containing a selective extractant of the general term . Its appearance and the general spherical spherical ion exchange resin the same, of which the active ingredient extractant. Therefore, it has the advantages of both ion exchange resin and extractant. It has the advantages of good hydraulics, less loss of extractant, long service life (higher than the extract-containing extraction chromatography with common carrier), simple packing, Fast and so on. In this paper, HDEHP extraction resin yttrium separation made some discussion, and successfully transported
