What is the meaning of Desorption?
The release of an adsorbed substance from a surface is referred to as desorption. This is the reversal of the sorption process. Desorption happens when the bulk phase and the adsorbing surface are in a condition of sorption equilibrium. As a result, lowering the bulk phase concentration causes some of the desorbed substance to revert to the bulk state. Desorption process helps the mobility of the mobile phase in chromatography.
