2.6: The Desorption Process - Chemistry LibreTexts

Adsorption, Absorption and Desorption - What's the Difference?
Desorption is the release of one substance from another, either from the surface or through the surface. Desorption can occur when an equilibrium situation is altered. Imagine a tank of water in equilibrium with its surroundings.
Desorption - an overview | ScienceDirect Topics
Desorption is a phenomenon contradictory to adsorption, which occurs as a final catalytic step in heterogeneous-catalyzed reactions. It involves the removal of surface-adsorbed species and makes the surface ready for further adsorption by new reactant molecules.
What is Desorption? - Definition & Process - Study.com
Desorption can be defined as a process where a previously adsorbed substance is released from a surface. Typically, desorption occurs when a given molecule gains enough energy...
Desorption - an overview | ScienceDirect Topics
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. From: Encyclopedia of Interfacial Chemistry ...
Desorption - an overview | ScienceDirect Topics
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 - (Intro to Chemistry) - Vocab, Definition ... - Fiveable
Desorption is the process by which adsorbed molecules or atoms are released from a surface or interface. It is the reverse process of adsorption, where molecules or atoms are attracted to and bind to a surface.
Adhesion of atoms, ions, bimolecules or molecules of gas, liquid or dissolved solids to a surface is called adsorption. This process creates a film of the adsorbate–the molecules or atoms being accumulated, on the surface of the adsorbent. General factors affecting adsorption: Nature of adsorbate and adsorbent.

Desorption is a key process in the phosphorus cycle that influences how much phosphorus is available for biological uptake. Factors like pH, temperature, and the chemical composition of the soil can greatly affect the rate of desorption.
Adsorption vs. Desorption: What's the Difference?
Dec 22, 2023 · Adsorption is the process where molecules adhere to a surface, while desorption is the reverse, where molecules detach from a surface. Adsorption is a surface phenomenon where atoms, ions, or molecules from a gas, liquid, or dissolved solid adhere to a surface.
