Key words: extraction, lanthanides(III), 5,7-dichloro-8-hydroxyquinoline
The extraction of Ln(III) (Pr, Nd, Sm, Eu) with 5,7-dichloro-8-hydroxyquinoline
in chloroform from water and water-methanol phase was studied. The parameters
of the extraction process were determined and the separation factors of
investigated pairs of lanthanides were calculated. In the presence of methanol
in water phase the synergistic effect was observed.
