“…Several authors have investigated the complexes formed between oxygen and nitrogen donating ligands and metal ions of Sc, Y and La using potentiometric methods [5,6,8,9]. Complexes formed between 8-Hydroxyquinoline 5sulfonic acid and Sc, Y and La have also been investigated in 0,1 M potassium nitrate ionic medium at 25,0 ºC [7].…”

This study aims to investigate the nature and types of complexes formed in aqueous solution between 8-Hydroxyquinoline (HQ) and the ions of Sc +3 , Y +3 , and La +3 . Potentiometric titration was used to follow the formation of complexes. The coordination compounds formed were studied through the determination of stability constants of these complexes in aqueous solution at 25,0 ± 0,1ºC and ionic strength of 0,1 M KNO 3 . The basicity of the ligand was also assessed by the determination of the dissociation constants of the ligand. All of the constants were determined by computer refinement of pH-volume data using the BEST computer program. Distribution diagrams for the species were drawn showing the concentrations of individual species as a function of pH by the SPE software program.

“…The results of those previous studies suggested that Sc(III) ion forms the most stable complexes in binary ligand system in aqueous solution. The complexes of Sc(III), Y(III), and La(III) formed in different ionic mediums have been the most adequate complexes to identify the coordination number and the structure of these complexes [4][5][6][7][8][9][10].…”

The interaction of Sc(III), Y(III), and La(III) ions with 1,10-phenanthroline (Phen) has been investigated, using the potentiometric method at 25 ± 0.1• C and I = 0.10 M KNO 3 . Collected potentiometric data were processed by the "BEST" software program to establish the complexation model for each system. SPE software program was used to evaluate the concentration distributions of the species formed in solution. The stability constants for the binary complexes increased as the ionic radii of the metal cations decreased.
