Abstract
Abstract Effects of different diluents on the extraction of cobalt(II) and indium(III) oxinate complexes have been studied using Co-60 and In-114m as radiotracers. Theory of regular solutions was applied for the determination of solubility parameters (δ) of cobalt oxinate and indium oxinate which were found to be 34.45 J1/2cm-3/2 and 34.03 J1/2 cm-3/2, respectively. Besides, distribution of each of the two complexes was studied in the mixtures of two solvents, assigned as good and poor solvents, in accordance with their individual behaviors. In both of the two cases, experimentally determined values of distribution-coefficient differed from those of calculated values which shows the importance of solute-solvent and solvent-solvent interaction in the present system.
