| 内容記述 | Enhancement of the extraction, or coextraction of lanthanide(III) (Ln) with metal(III) ions (M3+) such as Al3+, Sc3+, and Fe3+ was found in a typical chelate extraction system of 2-thenoyltrifluoroacetone (Htta)-benzene. The distribution ratio of La 3+ was enhanced by a factor of 6 with 3.0 x 10-2 M Al 3+, while that of Lu3+ was not affected at all. The magnitude of the coextraction decreased with the atomic number of Ln. Equilibrium analysis and spectroscopic studies indicated that the coextraction was ascribed to the formation of the 1:1 adduct between Ln(tta)3 and M(tta)3 extracted into the organic phase. The overall equilibrium of the coextraction was expressed as Ln3+ + M3+ + 6 Htta org ⇌ Ln(tta)3(M(tta)3)org + 6 H+. | |||||
