摘要
ＴｒｉｔｏｎＸ－１００的盐水溶液会分成聚合物固相和盐水相。这是一种新的非有机溶剂液－固萃取体系。研究了在该萃取体系中用ＮＨ４Ｉ作萃取剂，Ｐｄ（Ⅱ）、Ｂｉ（Ⅲ）、Ｚｎ（Ⅱ）和Ｆｅ（Ⅲ）等金属离子的萃取行为。实现了Ｂｉ（Ⅲ）—Ｆｅ（Ⅲ）和Ｐｄ（Ⅱ）—Ｚｎ（Ⅱ）间的定量萃取分离与测定。实验结果表明，金属离子与Ｉ－形成络阴离子被萃入聚合物固相。
An aqueous solution of Triton X-100 containing the salt can separate into the polymer solid phase and the salt aqueous phase. This is a new liquid-solid extraction system without organic solvents. the extraction behaviour of Pd(Ⅱ ), Bi(Ⅲ ),Zn(Ⅱ ) and Fe(Ⅲ ) was investigated by using NH4I as extractant in the liquid-solid extraction system. The quantitative extraction separation and determination of Bi (Ⅲ ) Fe (Ⅲ) and Pd (Ⅱ ) Zn (Ⅱ) were achieved. The experimental results indicate that the comples anions, formed by the metal ions with I, can be extracted into the Triton X-100 solid phase.
