Research paper: Adsorption Introduction The picture of Brunauer, Emmett and Teller 's model of multilayer adsorption The process which is called Adsorption is the adhesion of ions, atoms or molecules from different liquid, gas, or solid that dissolved to a surface. The process of adsorption produces a film of the adsorbate on the adsorbent surface. The process of adsorption is quite different from absorption. In absorption the fluid (that is adsorbate) is dissolved by or permeates a liquid or it can be solid (that is absorbent), respectively. Adsorption is a process which is surface-based whereas the absorption includes the whole volume of the material Like the surface tension, the process of adsorption is a result of surface energy. In a bulk material, whole requirements of bond (be they covalent, ionic, or metallic) of the constituent material atoms are filled by other atoms in the material. Nevertheless, atoms which are on the surface of the adsorbent aren’t fully surrounded by other adsorbent atoms and that is why they can attract adsorbates. The exact nature of the bonding has some dependencies. It depends on the details of the species involved, but the process of adsorption is
