Desorption

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). This occurs in a system being in the state of sorption equilibrium between bulk phase (fluid, i. Gas or liquid solution) and an adsorbing surface (solid or boundary separating two fluids). When the concentration (or pressure) of substance in the bulk phase is lowered, some of the sorbed substance changes to the bulk state.

Desorption a process in which atomic and molecular species residing on the surface of a solid leave the surface and enter the surrounding gas or vacuum. In stimulated desorption studies, species residing on a surface are made to desorb by incident electrons or photons.

We describe desorption of a dissolved gas in a semi-infinite melt, solidified by a one-dimensional heat flux.

During desorption, the smaller pores a and b will empty at their corresponding pressure, being lower than that needed for emptying of pore c. How ever, pore d can only empty via pore c and accordingly will empty at lower pressure. Encapsulated mesopores empty at lower pressure than the open pores of similar size.

The desorption process is an extremely important aspect of the adsorptionabsorption process, for understanding the mobility, bioavailability, and fate of chemicals in the environment. When the chemicals desorb from the mineral, the mineral can act as a constant source of chemicals to the surrounding solution.

Desorption electrospray ionization (desi) is an ambient ionization technique in which charged solvent droplets are made to hit the sample surface with rapid formation of analyte ions after the subject hits the sample surface.
