人们通常用仲胺和叔胺从酸性浸出液中萃取铀,虽对伯胺也作过研究,但萃取效率不佳。这三种烷基胺的萃取特性有许多类似之处:起萃取作用的是胺的盐类而不是游离胺;一般在酸性溶液中萃取金属离子;如果胺在有机相中以游离胺形式存在,需要先把它转成胺盐;为了防止胺盐水解释出游离 It is common to use secondary and tertiary amines to extract uranium from acidic leachate, although primary amines have also been studied, but the extraction efficiency is poor. There are many similarities in the extraction characteristics of these three alkylamines: the salts of the amine rather than the free amine act as the extractant; the metal ions are generally extracted in an acidic solution; if the amine is present as a free amine in the organic phase, Need to turn it into an amine salt; in order to prevent the amine salt hydrolysis to release free
