adsorption
adsorption The physical binding of a particle of a particular substance to the surface of another by adhesion or penetration. In soils it is the attachment of an ion, molecule, or compound to the charged surface of a particle, usually of clay or humus, where it may be subsequently replaced or exchanged. Ions carrying positive charges (e.g. those of calcium, magnesium, sodium, and potassium) become attached to, or adsorbed by, negatively charged surfaces (e.g. those of clay or humus).

adsorption
adsorption The formation of a layer of solid, liquid, or gas on the surface of a solid or, less frequently, of a liquid. There are two types depending on the nature of the forces involved. In chemisorption a single layer of molecules, atoms, or ions is attached to the adsorbent surface by chemical bonds. In physisorption adsorbed molecules are held by the weaker physical forces. The property is utilized in adsorption chromatography.
adsorption
adsorption Attraction of a gas or liquid to the surface of a solid or liquid.It involves attraction of molecules at the surface, unlike absorption which implies incorporation. The amounts adsorbed and the rate of adsorption depend on the structure exposed, the chemical identities and concentrations of the substances involved, and the temperature. Corrosion on the surface of a metal involves a chemical adsorption.
Adsorption
Adsorption
The removal of ions or molecules from solutions by binding to solid surfaces. Phosphorus is removed from water flowing through soils by adsorption on soil particles. Some pesticides adsorb strongly on soil particles. Adsorption by suspended solids is also an important process in natural waters.
adsorption
adsorption (ăd-sorp-shŏn) n. the formation of a layer of atoms or molecules of one substance on the surface of a solid or liquid of different substance. See adsorbent.
