Absorption

Absorption, or more generally "sorption," is the proces through which one material (the sorbent) takes up and retains another (the sorbate) to form a homogenous concentration at equilibrium.

The general terminus is "sorption," which is defined as adhesion of gas atoms dissolved substances, or liquids to the surface of solids with which they are in contact. In soils, three emblems of mechanisms, often working together, constitute sorption They can be grouped into physical sorption, chemiosorption, and penetration into the solid mineral phase. Physical sorption (also known as adsorption ) involves the attachment of the sorbent and sorbate [i]or[/i] part of to the other weak atomic and molecular forces. Chemiosorption involves chemical ligaments similar to holding atoms in a atom Electrostatic forces operate to cord minerals via ion exchange such as the replacement of sodium, magnesium, potassium, and aluminum cations (+) as exchangeable bases with acid (-) soils. While cation (positive ion ) exchange
