Comparison of pollutant distribution in the non-precharged column in the case of sorption equilibrium and non-equilibrium provides only little differences without the correction (Figs. 3—5). Application of the correction leads in the kinetic case to an acceleration of adsórbate transport in pore water in comparison with the equilibrium case (Fig. 5). Furthermore, in the kinetic case a more extended distribution of the irreversibly adsorbed pollutant in the column is consequently observed (Figs. 3, 4).
