Definition of adsorption in English English dictionary
The process by which a liquid or gas adsorbate is adsorbed by an adsorbent, forming a film on the adsorbent's surface
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 adhesion of a substance to the surface of another solid or liquid (not to be confused with absorption)
Attachment of the molecules of a gas or liquid to the surface of another substance This procedure is often used for the removal of a hazardous substance from water or air with activated carbon
The attachment of the molecules of a liquid or gaseous substance to the surface of a solid
The result of an attractive process that occurs at the surface of a liquid or solid as a result of physical or weak chemical forces between the adsorbent and the solute
The process of adhesion of the molecules of a gas, liquid or dissolved substance (in a condensed form) to a surface
Adsorption is a surface phenomenon that some products exhibit, whereby they form a physicochemical bond with substances Not to be confused with absorption
Adhesion of the molecules of gases, liquids, or dissolved substances to a solid surface, resulting in relatively high concentration of the molecules at the place of contact; e g the plating out of an anti-wear additive on metal surfaces
The process that causes one substance to be attracted to and stick to the surface of another substance, without actually penetrating its surface
The process by which chemicals are held on the surface of a mineral or soil particle
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
(1) The adherence of ions or molecules in solution to the surface of solids (2) The adherence of a gas, liquid, or dissolved material on the surface of a solid (3) The attraction and adhesion of a layer of ions from an aqueous solution to the solid mineral surfaces with which it is in contact An example is the adsorption of organic materials by activated carbon Not to be confused with Absorption
the adhesion of an extremely thin layer solid, liquid, or vapor molecules to the surface of a solid or liquid
the adhesion of a substance to the surface of a solid or liquid Adsorption is often used to extract pollutants by causing them to be attached to such adsorbents as activated carbon or silica gel Hydrophobic, or water-repulsing adsorbents, are used to extract oil from waterways in oil spills
A physical process of a gas, liquid or dissolved substance being taken up by (or glued to) the surface of a solid
The condensation of gas, liquids or dissolved substances on the surface of solids
(1) the concentration of molecules of a particular kind of the inter-face between the pigment and vehicle in screen printing inks, can effectively remove a component such as the drier from an ink vehicle; (2) a surface phenomena, in which liquid or gaseous molecules are retained on the surface of another substance; (3) the adhesion of molecules to a surface; (4) an effect of light striking an object where the light energy is absorbed and re-emitted at longer wavelenghts; (5) in optics, the loss in transmission of light, as through a transparent or translucent material
the accumulation of molecules of a gas to form a thin film on the surface of a solid
The adhesion of gases or liquid molecules to the surface of solids or liquids with which they are in contact
A type of adhesion which takes place at the surface of a solid or a liquid in contact with liquid or gases Adsorption results in the accumulation of molecules of gases, or ions or molecules of liquids, at the surfaces of contacting solids or liquids
Capability of a solid substance (adsorbent) to attract to its surface molecules of a gas or solution (adsorbate) with which it is in contact. Physical adsorption depends on van der Waals forces of attraction between molecules and resembles condensation of liquids. In chemical adsorption (often called chemisorption; see catalysis), the gas is held to the surface by chemical forces specific to the chemicals involved, and formation of the bond may require an activation energy
The accumulation of gases, liquids, or solutes on the surface of a solid or liquid At the HBEF scientists often examine how different compounds in the soil (e g , nitrate) adsorb, or attach, to soil particles
Describes what happens when a molecule from a fluid phase (gas or liquid) lands on the surface of a solid and stays, if only for a short while Adsorb is different from absorb (which see)
(verb) The collection of one substance on the surface of another, usually by electrostatic or van der Waals forces Examples: dust adsorbed on a table; garlic odor being adsorbed onto a jacket A pie thrown at the face of a clown is adsorbed by the clown Compare to "absorb"
A process where one element held in solution is attracted to and clings to another element In gold and silver processing the precious metals within the slurry in the leach tanks are adsorbed onto granules of activated carbon
