The invention relates to a process for the separation of amino acids and / or aminosulfonic acids from preferably aqueous solutions which contain them as impurities by adsorption of the amino acids on zeolites.n n n Solutions in which the method according to the invention can be used result, for. B. from the technical synthesis of oligopeptides, in which in some cases not insignificant residual concentrations of the amino acids serving as starting materials remain in solution together with the desired end product. |
