Kim, Seong-Yun published the artcileSelective Separation of Trivalent Europium(III) from Americium(III) using N,N’-Dimethyl-N,N’-di-2-phenylethyl-diglycol Amide (MPEDGA) Extractant in Ionic Liquid, HPLC of Formula: 110-99-6, the main research area is americium europium dimethyl diphenylethyl diglycol amide IL extractant separation.
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 ([C4mim][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 [HNO3] = 0.1 M, the maximum SFEu-152/Am-241 was obtained as 124. Moreover, with increase in the concentration of HNO3, the extraction ability decreased gradually, and SFEu-152/Am-241 decreased as 3 when [HNO3] reached 4 M. Back extraction was successfully completed by using 1 M guanidine carbonate with 0.5 M EDTA or 1 M guanidine carbonate with 0.5 M diethylenetriaminepentaacetic acid (DTPA), resp. Slope anal. revealed a 1:3 complex was formed. Effect of temperature further clarified the extraction process was exothermic.
Solvent Extraction Research and Development, Japan published new progress about Complexation. 110-99-6 belongs to class alcohols-buliding-blocks, name is 2,2′-Oxydiacetic acid, and the molecular formula is C4H6O5, HPLC of Formula: 110-99-6.
