Sorption


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" ;
; Adsorption: The physical adherence or bonding of ions and molecules onto the surface of another phase ;
; Ion exchange: An exchange of ions between two electrolytes or between an electrolyte solution and a 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.
