SURFACE DIFFUSION COEFFICIENT IN AQUEOUS PHASES ADSORPTION ON MACRORETICULAR ADSORBENTS

Recently, the authors reported that liquid-phase adsorption equilibria of phenols on macroreticular polymeric adsorbents (MRresins) such as Amberlite XAD-4and XAD-7were satisfactorily represented, over a wide range of concentration, by the equation of Jossens et al., derived thermodynamically on the basis of a heterogeneous surface adsorption theory.2} The equation has three parameters, //, K and p:
