Abstract
Chromatography of 25 nickel(II) amino acid chelates on silica gel using phenol-water 75:25 (w/w) as solvent system was described. In general, it was found that adsorbability of complexes formed with terdentate ligands is greater than that of complexes formed with bidentate ligands. In other cases RF values increased with the increasing number of carbon atoms present in the chelate molecule. Steric effects of side chains of amino acids, which influenced the degree of solvation of nickel ion, were also considered.Keywords
