WebDuring ion exchange mobile ions from an external solution are exchanged for ions that are electrostatically bound to the functional groups contained within a solid matrix. R – H + … Web1 jan. 1989 · The adsorption results in the formation of a molecular layer of the adsorbate on the surface. Often an equilibrium concentration is rapidly formed on the surface and is sometimes followed by a slow diffusion into the particles of the adsorbent. Ion exchange is an exchange of ions between a liquid and a solid phase.
