(r) a chemical adsorption process in which weak chemical bonds are formed between gas or liquid molecules and a solid surface.
adsorption (especially when irreversible) by means of chemical instead of physical forces; "chemisorption of gaseous nitrogen on iron catalysts"
Irreversible adsorption due to the formation of chemical bonds between the molecules of sorbat and sorbent across the interface. Chemisorption is employed in the surface modification of pigments and substrates as more efficient than the physical adsorption.
type of adsorption characterized by a chemical reaction between the concentrated particles and the enriched surface
This is sorption caused by a chemical reaction with the packing. Most of these interactions are irreversible. They usually occur on packings with reactive functional groups such as silanol or bonded amino phases.
The binding of an adsorbate to the surface of a solid by forces whose energy levels approximate those of a chemical bond. Contrast with physisorption.
The process by which a liquid or gas is chemically bonded to the surface of a solid.
The assimilation of gas, vapor, or dissolved matter by the surface of another substance resulting from electron transfer and a bond-forming chemical reaction between the surface and the gas, vapor, or dissolved matter.
A process related to adsorption in which atoms or molecules of reacting substances are held to the surface atoms of a catalyst by electrostatic forces having about the same strength as chemical bonds.
Adsorption of a chemical onto a surface in which the strength of the interaction is somewhat stronger than pure physical adsorption, and more like a chemical bond. A bond strength of around 80 kJ molâˆ’1 is often taken to be indicative of a true chemical interaction. In some cases, it is thought that chemical modification of the adsorbed species occurs.
Chemisorption is a type of adsorption whereby a molecule adheres to a surface through the formation of a chemical bond, as opposed to the Van der Waals forces which cause physisorption.
