Abstract

Effect of ionic liquid 1-butyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide on the extraction of U(VI), Th(IV), and lanthanides(III) from nitric acid solutions with phosphorylureas RR'P(O)NHC(O)NHC₈H₁₇-n that differ in the nature of substituents at the phosphorus atom has been studied. A considerable synergistic effect has been revealed on the extraction of metal ions in the presence of the ionic liquid in organic phase. The stoichiometry of extracted complexes has been determined. The influence of extractant structure, organic diluent nature, and HNO₃ concentration in aqueous phase on the efficiency of metal ions extraction into organic phase has been considered.

离子液体对用磷酰脲从硝酸溶液中萃取锕系元素和镧系元素（III）的影响

摘要研究了离子液体 1-丁基-3-甲基咪唑鎓双[(三氟甲基)磺酰基]亚胺对从硝酸溶液中萃取铀(VI)、钍(IV)和镧系元素(III)的影响。结果表明，在有机相中离子液体的存在下，金属离子的萃取具有相当大的协同效应。确定了萃取络合物的化学计量学。考虑了萃取剂结构、有机稀释剂性质以及水相中 HNO3 浓度对金属离子萃取到有机相的效率的影响。
