Description:
Addition of small (1–5 vol %) amounts of ionic liquids (ILs) increases the Am(III) distribution ratio in the system with diphenyl(dibutylcarbamoylmethyl)phosphine oxide (Ph 2 Bu 2 ) by more than 2 orders of magnitude. With 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ([C 4 mim] + Tf 2 N − ) used as IL, the Am(III) extraction is possible even from 8 M HNO 3 , which is important in radiochemical analysis of process and environmental samples, because many procedures are based on the transfer of solid samples into 8 M HNO 3 . The extraction data show that the extractable Am(III) complex contains three Ph 2 Bu 2 ligands, an IL anion, and two NO 3 − anions.
