Popis:	Extraction of lanthanides and actinides from nitric acid solutions with N-(diphenylphosphoryl)-N'-n-propylureas containing imidazolyl, diethylamino, pyrid-2-yl, 2-oxopyrrolidino fragments in the ω position of the alkyl substituent has been studied. It has been shown that Ho(III) and Yb(III) related to the yttrium subgroup of lanthanides are extracted much better than La(III) and Nd(III) related to the cerium subgroup. N-(Diphenylphosphoryl)urea containing ω-(2-oxopyrrolidino)propyl fragment at the terminal nitrogen atom shows the best extraction properties. This dependence has been theoretically explained by modeling complexation because the coordination of f-block element ion with amide oxygen atom is more preferable
