摘要

研究了双(2,4,4-三甲基戊基)膦酸(Cyanex 272)溶剂萃取法在氯水介质中分离钪(Sc)和钇(Y)。传统的斜率分析方法揭示了金属的萃取平衡公式。在cyanex272中，Sc的萃取力比Y强，分离系数高达2.82 × 105。即使使用高浓度的盐酸，也不能从负载的Cyanex272有机溶液中完全剥离Sc。在有机相中加入1-辛醇作为改性剂降低了Sc的可萃取性，导致Sc从负载的有机溶液中成功剥离。

Separation of Scandium from Yttrium in Aqueous Chloride Media by Solvent Extraction with an Acidic Phosphinate Extractant

Separation of scandium (Sc) from yttrium (Y) in aqueous chloride media was investigated by solvent extraction with bis(2,4,4-trimethylpentyl)phosphinic acid (Cyanex 272). Conventional slope analysis method revealed the extraction equilibrium formulation of the metals. Sc is more strongly extracted than Y by Cyanex 272, and the separation factor of the metals is quite high at 2.82 × 105. Complete stripping of Sc from the loaded organic solution of Cyanex272 could not be achieved, even with a high concentration of hydrochloric acid. Addition of 1-octanol as a modifier to the organic phase decreased the extractability of Sc, leading to successful stripping of Sc from the loaded organic solution.

期刊介绍： Solvent Extraction Research and Development, Japan (Solvent Extr. Res. Dev., Jpn.) is a periodical issued from Japan Association of Solvent Extraction (JASE) containing papers dealing with all aspects of solvent extraction and their related methods, underlying principles, and materials. Original articles, notes, technical reports, and critical reviews will be considered for publication. Original articles must be of reasonably broad scope and significance to the solvent extraction. Notes will originally describe novel work of a limited nature or especially significant work in progress. Authors can contribute some information of novel techniques, equipment or apparatus, reagents and diluents for solvent extraction as technical reports. Critical reviews will be received from the authors to whom the editorial committee asked to contribute.
