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
