Abstract

In a process for separating aminoacids from a mixture containing them using non-exchange resins, the mixture is passed successively over several columns arranged in series and filled respectively with an absorptive material, a first ion-exchange resin, and a second resin which exchanges oppositely-charged ions. Preferably the mixture is passed at least once succesively over the same two columns of anion and cation-exchange resins. Each column can be previously oxidized by an oxidizing agent. This process permits a high degree of separation of a complex mixture of amino acids derived, in particular, from the hydrolysis of proteins without the addition of external agents.
