Method For Purifying Aromatic Amino Acids |
| 摘要 |
A method for purifying an amino acid from an initial mixture is disclosed, in which the amino acid includes an aromatic ring and has an acidity constant Ka, the method including:
a first step of putting the initial mixture into contact with a strong cation resin, at a pH greater than or equal to pKa; anda second elution step with an aqueous solution of eluent having a pH greater than the pH of the first step, giving the possibility of collecting a flow enriched in the amino acid. |

1. A method for purifying an amino acid from an initial mixture, in which the amino acid includes an aromatic ring and has an acidity constant Ka, the method comprising:
(a) a first step of putting the initial mixture into contact with a strong cation resin, at a pH greater than or equal to pKa; and (b) a second elution step with an aqueous solution of eluent having a pH greater than the pH of the first step, making it possible to collect a flow enriched in the amino acid. |
