Abstract

The effects of slightly nonlinear equilibria and axial dispersion on the performance of a packed bed of ion exchange resin used for the sorption of nonelectrolytes were studied. Experiments with dilute aqueous solutions of acetone and ethylene glycol show that these effects lead to false estimates of the intraparticle diffusivity of the solute within the resin beads when a linear model is used to analyze the data. However, predictions based on a representative computer model are in close agreement with data.
