英文摘要
In order to discuss the details of synergistic extraction of lanthanoids(III) with beta-diketones (TTA and pivaloyltrifluoroacetone) and aromatic amines, the residual hydration numbers of lanthanoids(III) in the beta-diketonato chelates and the adducts of the chelates with the amine, and the complexation heat as well as the adduct formation constants have been determined. In addition, the interaction between the donor atom in the amine and the acceptor atom in organic solvents such as H in chloroform has been examined from IR spectra measured.
