摘要：

Extraction properties toward actinides and lanthanides of phosphorylketones on varying the number of functional phosphoryl and carbonyl groups in the structure of organic ligand have been modeled. Presented data have shown that the studied phosphorylketones I-III as extractants display higher extraction ability 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 be used for the selective recovery and preconcentration of U(VI) from nitric acid solutions
