Characterization of dynamic behaviour of Cd(II) and Zn(II) uptake from a binary solution onto the fixed zeolite bed

Cd(II) and Zn(II) ions were successfully removed from the equimolar binary aqueous solution by the column process. Two experiments were conducted with the 80 mm fixed bed of natural zeolite, at the flow rate of 1 ml/min. The obtained S-shape breakthrough curves and regeneration curves almost completely overlap, indicating that the compactness of the zeolite layer, reproducibility and stationary conditions were achieved. The dynamic behaviour in the packed column reactor has been examined according to the Advection-Dispersion-Reaction (ADR) model and kinetic parameters have been estimated.
