Desorption is the process by which a substance, typically a gas or liquid, is released from or is no longer adherent to a solid surface. It is the opposite of adsorption, where molecules adhere to a surface. Desorption can occur due to various factors, such as changes in temperature, pressure, or concentration. In environmental science, desorption is significant in understanding pollutant release from soils or sediments.

Desorption releases material previously retained at a boundary. At chemical equilibrium, adsorption and desorption can both continue while their mean rates balance.
