摘要：
The extraction of f-elements from nitric acid solutions with symmetric diglycolamides in polar aliphatic fluorinated diluents was studied. The influence of diamide structure, namely of the length of alkyl substituents (C4, C6, C8) on amidic nitrogen atom, on the extraction properties was investigated. New extraction solvent on the base of N,N,N′,N′-tetrahexyl diglycolamide in formal of tetrafluorpropyl alcohol (FN-1) was proposed for selective Am (III) separation from PUREX-process raffinates.
