摘要

合成了一种基于二乙醇酰胺的N, N ' -二甲基- N, N ' -二-2-苯基乙基二甘醇酰胺(MPEDGA)萃取剂，并将其溶解于1-丁基-3-甲基咪唑非氟丁磺酸盐([c4mim][NfO])中制备萃取相。研究了其在硝酸溶液中Am-241与Eu-152的分离性能。萃取动力学快速，可在15 min内达到平衡。当[hno3] = 0.1 M时，eu152 / Am-241的最大SF为124。随着hno3浓度的增加，萃取能力逐渐降低，当[hno3]浓度达到4 M时，SF Eu-152/ Am-241降低为3，分别用1 M碳酸胍与0.5 M乙二胺四乙酸(EDTA)或1 M碳酸胍与0.5 M二乙三胺五乙酸(DTPA)完成反萃取。坡度分析显示形成了1:3的络合物。温度的影响进一步明确了提取过程是放热的。

Selective Separation of Trivalent Europium(III) from Americium(III) using N,N′Dimethyl-N,N′-di-2-phenylethyl-diglycol Amide (MPEDGA) Extractant in Ionic Liquid

A diglycolamide based N , N ′ -Dimethyl- N , N ′ -di-2-phenylethyl-diglycol amide (MPEDGA) extractant was synthesized and dissolved into 1-butyl-3-methylimidazolium nonafluorobutanesulfonate ([C 4 mim][NfO]) to prepare the extraction phase. Its separation performance of Am-241 with Eu-152 in nitric acid solution was investigated. The extraction kinetics were fast and could reach equilibrium within 15 min. When [HNO 3 ] = 0.1 M, the maximum SF Eu-152/ Am-241 was obtained as 124. Moreover, with increase in the concentration of HNO 3 , the extraction ability decreased gradually, and SF Eu-152/ Am-241 decreased as 3 when [HNO 3 ] reached 4 M. Back extraction was successfully completed by using 1 M guanidine carbonate with 0.5 M ethylenediaminetetraacetic acid (EDTA) or 1 M guanidine carbonate with 0.5 M diethylenetriaminepentaacetic acid (DTPA), respectively. Slope analysis revealed a 1:3 complex was formed. Effect of temperature further clarified the extraction process was exothermic.

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.
