The removal of furfural from water by adsorption with polymeric resins

The removal of furfural from water by adsorption on a polymeric resin XAD-4 was studied. Equilibrium isotherm measurements were made and column dynamic data collected under various sets of operating conditions. The axial-dispersed plug-flow model was used to simulate the experimental data. The linear driving force parameters required in these simulations were determined independently of the column measurements, providing a more versatile simulation model. The model predicts the breakthrough curves with a fair degree of accuracy.
