A systematic study of extraction systems for the separation of f -elements using the tetradentate N,O-donor diamide of 1,10-phenanthroline-2,9-dicarboxylic acid ( L ) in various molecular and ionic solvents was performed. It was demonstrated that the nature of a diluent has a significant impact on solvent extraction of Am(III) and Ln(III) and the stoichiometry of formed complexes with f -elements. The mechanism of complexation and forms of complexes in different diluents were investigated by radiometric methods, UV-vis titration, and XRD. |
