Abstract
The present disclosure relates to a process for separation of enantiomers of the amino acid from a racemic mixture.The process comprises electrolyzing the first electrolyte having 1 molar solution of lithium perchlorate and 0.01 molar solution of racemic mixture of amino acid in an electrochemical cell containing a working electrode having polycrystalline metal surface configured to adsorb L-enantiomer of amino acid using a saw-tooth current. Further, the polarity of the saw-tooth current is reversed to de-adsorb the L-enantiomer of amino acid from the working electrode into the second electrolyte re-filled in the cell. The process of the present disclosure to separate enantiomer of amino acid from a racemic mixture is simple and economical.
