"An increase of the concentration of a solute in the vicinity of a solid surface, over that in the bulk of the solution, due to the attractive interaction between the solid immersed into the solution and the solute. Adsorption on a solid from a gaseous phase also occurs. It is a surface process, not to be confused with absorption. Opposite: desorption. "
The attachment of a particle, ion or molecule to a surface. Calcium is adsorbed onto the surface of clay or humus.
The attachment of a particle, ion or molecule to a surface. Calcium is adsorbed onto the surface of clay or humus.
A separation process for removing impurities based on the fact that certain highly porous materials fix certain types of molecules onto their surface.
The adhesion of gases or liquid molecules to the surface of solids or liquids with which they are in contact.
The adhesion of the molecules of gases, dissolved substances, or liquids in more or less concentrated form, to the surface of solids or liquids with which they are in contact. Commercial adsorbent materials have enormous internal surfaces.
Retention (of water vapor) as a surface layer on a material ..technical glossary, technical terms, glossary, technical glossary
The process of interaction between the solute and the surface of an adsorbent. The forces involved can be strong (for example, hydrogen bonds) or weak (van der Waals forces). For silica gel, the silanol group is the driving force for adsorption, and any solute functional group that can interact with this group can be retained by liquid-solid chromatography on silica.
Adsorption Definition from Encyclopedia Dictionaries & Glossaries
Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent. This process differs from absorption, in which a fluid (the absorbate) permeates or is dissolved by a liquid or solid (the absorbent). Note that adsorption is a surface-based process while absorption involves the whole volume of the material. The term sorption encompasses both processes, while desorption is the reverse of adsorption. It is a surface phenomenon.

Adsorption Definition from Society & Culture Dictionaries & Glossaries
Removal of a pollutant from air or water by collecting the pollutant on the surface of a solid material; e.g., an advanced method of treating waste in which activated carbon removes organic matter from waste-water.

Adhesion of the molecules of a gas, liquid or dissolved substance to a surface. Adsorption differs from absorption in that adsorption is the assimilation or incorporation of a gas, liquid, or dissolved substance into another substance.
