Separation of optical isomers of amino acids on modified chitin and chitosan layers

Abstract

The possibilities of separation of seven D,L-mixtures of amino acids on chitin, chitosan beds and their modifications are tested, using TLC methods. From investigated stationary phases chitin modified by Cu2+ ions may be used for separation of optical isomers of amino acids. The best results have been obtained in chromatographic systems with ternary mobile phases.
