Abstract

A method for separating a basic amino acid from a liquor containing the same, which entails (a) contacting the basic amino containing liquor with a strongly acidic cation exchange resin at a pH at which the basic amino acid exists in the form of a divalent cation, thereby adsorbing at least a part of the basic amino acid in the form of the divalent cation; (b) contacting said ion exchange resin with a liquor containing said basic amino acid and a neutral amino acid or an acidic amino acid at a pH at which the basic amino acid exists in the form of a monovalent cation; (c) passing an eluant through said ion exchange resin, thereby eluting the basic amino acid from the ion exchange resin; and (d) separating and recovering the basic amino acid from the eluate.
