AI overview

Adsorption is a process where molecules stick to the surface of a material, forming a layer on top of it. This matters because scientists use models like the BET model to understand how many molecules can attach to surfaces, which is important for applications like purifying water, filtering air, and manufacturing chemicals.

thumb|Brunauer, Emmett, and Teller's #BET|model of multilayer adsorption is a random distribution of molecules on the material surface.

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). While adsorption does often precede absorption, which involves the transfer of the absorbate into the volume of the absorbent material, alternatively, adsorption is distinctly a surface phenomenon, wherein the adsorbate does not penetrate through the material surface and into the bulk of the adsorbent. The term sorption encompasses both adsorption and absorption, and desorption is the reverse of sorption.
