Sorption

Source: Wikipedia, the free encyclopedia.

Gas–liquid absorption (a) and liquid–solid adsorption (b) mechanism. Blue spheres are solute molecules.

Sorption is a physical and chemical process by which one substance becomes attached to another. Specific cases of sorption are treated in the following articles:

Absorption
"the incorporation of a substance in one state into another of a different state"
gases
being absorbed by a liquid);
Adsorption
The physical adherence or bonding of
catalyst
surface);
Ion exchange
An exchange of
complex
.

The reverse of sorption is desorption.

Sorption rate

The adsorption and absorption rate of a diluted solute in gas or liquid solution to a surface or interface can be calculated using Fick's laws of diffusion.
