Adsorption

Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent. This process differs from absorption, in which a fluid (the absorbate) is dissolved by or permeates a liquid or solid (the absorbent), respectively. Adsorption is a surface phenomenon, while absorption involves the whole volume of the material, although adsorption does often precede absorption. The term sorption encompasses both processes, while desorption is the reverse of it. Similar to surface tension, adsorption is a consequence of surface energy. …

(King and Briggs 2020) is the kinetics of Cu2+ adsorption and desorption on bentonite in compacted systems There are many studies of the kinetics of Cu2+ adsorption/desorption in loose clay systems, but the resulting potential (ECORR) when modelled using the CCM. (The adsorption/desorption of Cu2 have a significant effect on the compacted clay. It is difficult to study adsorption/desorption kinetics of compacted clay systems because of the uncertain impact of diffusion on the adsorption/desorption kinetics. Compacted bentonite is used
