  • Surface Chemistry (Part-2)

    A physical adsorption process in which there are van der Waals forces of interaction between gas or liquid molecules and a solid surface. Chemisorption involves a chemical reaction between the surface and the adsorbate. It is a type of adsorption

  • Surface Chemistry (Part-1)

    Process of adsorption is similar to absorption, by which a substance in a gas or liquid becomes attached to a solid. The substance can be a pollutant, called an adsorbate, which is attracted to the surface of a special solid.
