Definitions for "Chemisorption"
(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.
