INTRAPARTICLE TRANSPORT OF AMINO-ACIDS IN A CATION-EXCHANGER

Intraparticle transport of amino acids, phenylalanine and tryosine, in a macroreticular cation-exchange resin, Amberlite 200, was investigat ed in a finite batch adsorber. A transport model was developed based o n the consecutive diffusion of the amino acids through liquid-filled m acropores and microspheres. The latter was further simplified by the l inear driving force approximation (LDFA) since the microspheres are qu ite small. The model was used satisfactorily for simulating and predic ting the performance of finite batch operations.
