Title
Modelling of fixed-bed adsorption of mono-, di-, and fructooligosaccharides on a cation-exchange resin
Abstract

Kinetics of fixed-bed adsorption of simple saccharides (glucose, fructose, and sucrose) and fructooligosaccharides (1-kestose, 1-nystose, and 1F-fructofuranosyl nystose) on process-size particles of cation exchanger Amberlite™ CR1320Ca was investigated. A step-up method of frontal chromatography was used when several inlet concentration steps were made in the range of 0–20 g dm−3. The obtained experimental data were fitted simultaneously using the general rate model with two estimated parameters, which were the distribution coefficient of linear adsorption isotherm and solid-phase diffusion coefficient. The contribution of individual transport phenomena to dispersion of adsorption fronts was discussed.
