adsorption

 [ad-sorp´shun]
the action of a substance in attracting and holding other materials or particles on its surface; see also absorption.
attachment (def. 2).

ad·sorp·tion

(ad-sōrp'shŭn), Do not confuse this word with absorption.
The property of a solid substance of attracting and holding to its surface a gas, liquid, or a substance in solution or in suspension, for example, condensation of a gas onto a surface. Compare: absorption.
[L. ad, to, + sorbeo, to suck up]

adsorption

/ad·sorp·tion/ (ad-sorp´shun) the action of a substance in attracting and holding other materials or particles on its surface.

adsorption

[adsôrp′shən]
Etymology: L, ad + sorbere, to suck in
a natural process whereby molecules of a gas or liquid adhere to the surface of a solid. The phenomenon depends on an assortment of factors such as surface tension and electrical charges. Many biological reactions involve adsorption. Adsorption is the principle on which chromatography is based and which allows for the separation of a mixture into component fractions for qualitative analysis. See also chromatography. adsorb, v.

Adsorption

Chemistry An accumulation/concentration of molecules of a gas or liquid on a surface interfacing with the gas or liquid, resulting in a relatively high surface concentration.
Histology The accumulation of a substance on a surface affected by the affinities of acids to bases—and vice versa—based on electrical attraction; adsorption may explain differential affinity for dyes that occurs in histologic preparations of tissues being examined by light microscopy.
Immunology The removal of nonspecific agglutinins, by incubating the fluid of interest in a serum—e.g., of bovine origin—which lacks the antigens to be measured.
Virology The adhesion of a substance to an organic particle in a solution—e.g., adhesion of a virus to a cell.

ad·sorp·tion

(ad-sōrp'shŭn)
The property of a solid substance to attract and hold to its surface a gas, liquid, or a substance in solution or in suspension.

adsorption

The process by which a substance, such as a gas or dissolved solid, is attracted to, and adheres to, a surface.

adsorption

the taking up of gas or liquid by a surface or interface. In physical adsorption, molecules are held by VAN DER WAAL'S FORCES of attraction; in chemical adsorption there is exchange or sharing of electrons. Compare ABSORPTION.

Adsorption

The binding of a chemical (e.g., drug or poison) to a solid material such as activated charcoal or clay.
