摘要
近年来,对锂溶剂萃取体系的研究主要集中在四个方面:醇类和酮类、烷基膦和磷酸酯类、混合离子萃取剂类以及冠醚类。其中尤以冠醚引人注目。小量值的十四元环四氧羧酸冠醚是最有希望的优良锂萃取剂。
In recent years, the research, on solvent extract systems of lithium was mainly centralized on four aspects: alcohols, alkyl phosphins, blended ion extractants and crown ethers. Among them the crown ethers is the most conspicuous. The small molecular weight crown ethers with 14-membered macrocyclic ring and four ring oxygens have brilliant prospects as lithium extractant.
