adsorbent?

Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface.[1] 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.[2]
