| Abstract: | The extraction of copper(II) 8-hydroxyquinolinate, 5,7-dichloro-8-hydroxyquinolinate and 2-thenoyltrifluoroacetonate was investigated
and the stability constants and distribution constants of the complexes were determined. The dependence of thepH values for 50% extraction and of the distribution constants of the copper complexes on the dissociation constants and distribution
constants of the corresponding agents are discussed. |
