Abstract

Published data on the application of ionic liquids (ILs) and binary extractants in the extraction and separation of rare-earth metals (REMs) and radioactive elements, published in Russia and abroad during the last 5–10 years, are reviewed. An analysis of published studies demonstrated that new ILs used as solvents or additives to improve the extraction and separation of actinides and lanthanides are being presently developed. Difunctionalized and also binary extractants are widely used to separate REMs. Various extractive systems with ILs and factors affecting the efficiency of extraction and separation of actinides and lanthanides are considered and attention is given to the composition of compounds of the elements being extracted, selectivity of extractants, possibility of re-extracting metals from the organic phase, and practical use of ILs.

离子液体和二元萃取剂在镧系元素和Act系元素的萃取分离中的应用趋势

摘要

回顾了过去5到10年间在俄罗斯和国外发布的有关离子液体（ILs）和二元萃取剂在稀土金属（REMs）和放射性元素的提取和分离中应用的公开数据。对已发表研究的分析表明，目前正在开发用作溶剂或添加剂以改善act系元素和镧系元素的萃取和分离的新IL。双官能化的萃取剂和二元萃取剂被广泛用于分离REM。考虑了各种具有IL和影响affecting系元素和镧系元素的提取和分离效率的因素的提取系统，并关注所提取元素的化合物组成，提取剂的选择性，从有机相中再提取金属的可能性， IL的实际使用。
