Smith和Page首先报导了长碳链脂肪胺与酸结合的性质。胺与酸生成的盐不溶于水而溶于有机溶剂。嗣后Moore用于萃取各种金属络合酸,为胺类萃取剂开辟了新用途。近年来许多作者将它推广应用于各种金属离子的萃取。在核燃料提纯与回收方面受到特别重视,在无机物分离与分析方面应用也日益广泛。已见不少有关的文献总结。本文拟就胺类萃取剂在分析化学上的应用作一简要的概述。一、胺类萃取剂介绍胺类萃取剂按其性质一般可分为伯胺、仲胺、叔胺
Smith and Page first reported the long-chain fatty amine-acid binding properties. Amines and acid-derived salts are insoluble in water and soluble in organic solvents. Later, Moore used to extract a variety of metal complex acid, opened up new uses for amine extractant. In recent years, many authors promote it for various metal ion extraction. Special attention has been paid to the purification and recovery of nuclear fuel, and its application in the separation and analysis of inorganic substances has also become increasingly widespread. Have seen a lot of relevant literature summary. This article intends to amine extractant in the analytical chemistry of a brief overview. First, the introduction of amine extractants Amine extractants can be divided according to their nature can be divided into primary amine, secondary amine, tertiary amine
