Аннотация:Extraction properties toward actinides and lanthanides of phosphorylketones on varying the numberof functional phosphoryl and carbonyl groups in the structure of organic ligand have been modeled. Presenteddata have shown that the studied phosphorylketones I–III as extractants display higher extractionability with respect to lanthanides as compared with TBP, TOPO, and CMPO. 4,4-Bis(diphenylphosphoryl)butan-2-one III exhibits high extraction ability and selectivity toward U(VI). This compound can beused for the selective recovery and preconcentration of U(VI) from nitric acid solutions
