烷基亚砜是继有机膦萃取剂之后又发展的一种新型萃取剂,近年来已广泛用于铀、钍、稀土、锆、铪和贵金属的分离测定中。烷基亚砜含有半极性硫-氧基团>S→O,它们能有效地与许多金属离子和金属-配位体络合物生成溶剂化合物。二正辛基亚砜是其中应用较多的一种中性烷基亚砜萃取剂,有关二正辛基亚砜的溶剂萃取和反相纸色层行为已经有系统的研究。本文只介绍二正辛基亚砜的合成方法及其在锆铪萃取色层分离中的应用。
Alkyl sulfoxide is a new extractant developed after organic phosphine extractant. It has been widely used in the determination of uranium, thorium, rare earth, zirconium, hafnium and precious metals in recent years. Alkyl sulfoxides contain semipolar sulfur-oxygen groups> S → O, which effectively form solvates with many metal ions and metal-ligand complexes. Di-n-octyl sulfoxide is one of the most widely used neutral alkyl sulfoxide extractants. There have been many systematic studies on the solvent extraction and anti-color paper layers of di-n-octyl sulfoxide. This article only describes the synthesis of di-n-octyl sulfoxide and its application in zirconium-hafnium extraction chromatography color separation.
