Asymmetric resins containing optically active bi-or tridentate a-amino acids as fixed ligands coordinated with Cu 2+, NiZ+ or other transition metal ions can be used for the ligand-exchange chromatography of racemic a-amino acids. The degree of resolution of enantiomers depends both on the nature of
A ligand-exchange chromatographic procedure for the selective separation of amino acids from inorganic ions is presented. It was found that the binding of amino acids to the nickel-Chelex 100 resin is pH dependent. At pH 8.5-9. I, only the basic amino acids lysine, histidine and arginine are quantit
