Desorption - Wikipedia
网页Desorption is the physical process where adsorbed atoms or molecules are released from a surface into the surrounding vacuum or fluid. This occurs when a molecule gains enough energy to overcome the activation barrier and the binding energy that keep it attached to the surface. [1]

Desorption - an overview | ScienceDirect Topics
网页Desorption represents an emission process of chemical species on a solid surface. There are two cases: (i) the emission of the species without chemical conversions just after breaking its bond with surface atoms, and (ii) emission of new molecules following a chemical reaction of the species (association or decomposition).
Desorption - an overview | ScienceDirect Topics
网页Desorption refers to the process of chemical species being emitted from a solid surface, either without chemical conversions or after a chemical reaction. The rate of desorption depends on factors such as the density of the species, the strength of bonding to the surface, and the surface temperature.
Kinetics of Adsorption, Desorption and Reactions at Surfaces
网页We review the kinetic theories of adsorption, desorption, surface diffusion, and surface reactions, emphasizing the physics and chemistry underlying these processes. In particular, the need for local equilibrium in setting up macroscopic rate equations is discussed...
