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" (e.g., liquids being absorbed by a solid or gases being absorbed by a liquid);

Adsorption

The physical adherence. Or bonding of ions and molecules onto the——surface of another phase (e.g., reagents adsorbed to a solid catalyst surface);

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.
