Abstract

The extraction of Co(III) from aceticacid-acetate buffer solutions with various mixtures of ligands has been studied. Thenoyltrifluoroacetone mixed with triphenylphosphine oxide, trioctylphosphine oxide or tributyl phosphate were used as extractants. The effect of different parameters affecting the distribution ratio was studied in detail. Also, the corresponding thermodynamic parameters are calculated and discussed, together with the structures of extracted species.
