Physical or chemical process by which one substance becomes attached to another
Gas–liquid absorption (a) and liquid–solid adsorption (b) mechanism. Blue spheres are solute molecules.
Sorption is aphysical andchemical process by which onesubstance becomes attached to another. Specific cases of sorption are treated in the following articles:
"the incorporation of a substance in one state into another of a different state"[1] (e.g.,liquids being absorbed by asolid orgases being absorbed by a liquid);
The adsorption and absorption rate of a diluted solute in gas or liquid solution to a surface or interface can be calculated usingFick's laws of diffusion.
