许多三元络合物的优良可萃性已成为萃取分离和萃取光度法的重要组成部分。本文从几种类型三元络合物的可萃机理入手,总结其形成规律、分析特性及分析应用和发展趋势。多元离子缔合物多元离子缔合物是溶剂萃取中的一种重要类型。其中碱性有机染料和高分子胺体系较重要,近年来发展起来的冠醚体系缔合物也值得注意。碱性有机染料体系离子缔合物形成多元离子缔合物的碱性染料主要有:三苯甲烷染料,醌亚胺类碱性染料,呫吨类染料,安替匹林及其衍生物。
The good extractability of many ternary complexes has become an important part of extraction and extraction and extraction spectrophotometry. This article starts from the extractable mechanism of several types of ternary complexes, summarizes its formation law, analysis characteristics and application and development trend. Multiple ion association Multiple ion association is an important type of solvent extraction. Among them, basic organic dyes and polymer amine systems are more important. In recent years, crown ether system complexes have also been noticed. Alkaline organic dye system Ion-association compounds to form multiple ion-association of basic dyes are: triphenylmethane dyes, quinone imine basic dyes, xanthene dyes, antipyrine and its derivatives.
