Abstract

In the present work the experimental kinetic data of amino acid reactive sorption on solvent impregnated resins (SIR) and its mathematical description is presented. L-Phenylalanine (L-Phe) is extracted from aqueous solution when impregnating the liquid ion-exchanger tricaprylylmethylammonium chloride (TCMAC) on XAD-resin. Experiments with different resins, ion-exchanger loadings, and L-Phe concentration were made for the determination of the rate controlling mechanism. The experimental results, confirmed by the analysis with the modified shrinking-core model, are in favor of a rate-determining intraparticle kinetics. With respect to its adequate description, three different models were considered. The first is based on Fick's diffusion law, the second one assumes the reaction as a rate determining step, and the third model is a combination of both. [ABSTRACT FROM AUTHOR]
