Process for separating and/or isolating organic compounds which are soluble in water, some of which are adsorbed on finely divided inorganic solids, by adsorption of this fraction and isolation of the loaded solid, which is characterised in that

Cross-flow filtration process for separating organic compound by

The invention relates to a process for removing amino acids and/or aminosulphonic acids from preferably aqueous solutions which contain these as impurities by adsorbing the amino acids on zeolites. Solutions to which the process according to the invention can be applied are produced, for example, from the industrial synthesis of oligopeptides in which the amino acids serving as starting materials are always present in solution, sometimes to a not inconsiderable residual concentration, together with the desired end product.

Process for separating amino acids and aminosulponic acids through

A process for the separation of amino acids from aqueous solutions by adsorption on zeolites of different types. It is unnecessary to separate the biomass prior to the treatment.
