The major difference between adsorption and absorption is that one is a surface process and the other a bulk process. Adsorption. Adsorption is a surface process, the accumulation of a gas or liquid on a liquid or solid. Adsorption can be defined further based on the strength of the interaction between the adsorbent (the substrate onto which chemicals attach) and the adsorbed molecules. Chemisorption involves more energy than physisorption.
