Separation method of amino acids |
| abstract |
A method is provided for the separation of at least one aromatic amino acid from an aqueous solution of mixed amino acids including the aromatic amino acid. The aqueous solution is brought into contact with a strongly acidic gel-type cation exchange resin which has been converted into a salt with an alkali metal or an alkaline earth metal, whereby the aromatic amino acid is selectively sorbed by the cation exchange resin. The aromatic amino acid thus sorbed can then be desorbed from the ion exchange resin, preferably with water. |
