Adsorption vs. Desorption

Adsorptionnoun

The adhesion of a liquid or gas on the surface of a solid material, forming a thin film on the surface.

Adsorptionnoun

the process by which molecules of a substance form a thin film on the surface of a solid. Distinguished from absorption, in which the foreign substance penetrates the body of the absorbing material.

Adsorptionnoun

the accumulation of molecules of a gas to form a thin film on the surface of a solid

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.

Desorptionnoun

The process in which atomic or molecular species leave the surface of a solid and escape into the surroundings; the reverse of absorption or adsorption.

Desorptionnoun

changing from an adsorbed state on a surface to a gaseous or liquid state

Desorptionnoun

the release of an adsorbed substance from a surface

Desorption

Desorption is a phenomenon whereby a substance is released from or through a surface. The process is the opposite of sorption (that is, either adsorption or absorption).
