Abstract

So far it is not possible to predict adsorption equilibria only by the physical properties of adsorbate, adsorbent and solvent. The main problem of the quantification of the adsorption behavior is the missing possibility to characterize the surfaces of solids. This paper shows various possibilities for the predictions of adsorption equilibria at low concentrations in the aqueous phase. The most promising way is the use of a dielectric continuum model because it does not only supply a prediction possibility in the area of very small concentrations on a certain adsorbent, but represents a complete new way for the characterization of heterogeneous surfaces.
