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。
The brine solution of Triton X-100 is divided into a polymer solid phase and a brine phase. This is a new non-organic solvent liquid-solid extraction system. The extraction behavior of metal ions such as Pd (Ⅱ), Bi (Ⅲ), Zn (Ⅱ) and Fe (Ⅲ) with NH4I as extractant in the extraction system was studied. The quantitative extraction, separation and determination of Bi (Ⅲ) -Fe (Ⅲ) and Pd (Ⅱ) -Zn (Ⅱ) were achieved. The experimental results show that metal ions and I-forming complex anions are extracted into the polymer solid phase.
