New Post                     Adsorption.                  Adsorption  is the  adhesion  of  atoms ,  ions  or  molecules  from a gas, liquid or dissolved solid to a  surface . [1]  This process creates a film of the  adsorbate  on the surface of the  adsorbent . This process differs from  absorption , in which a  fluid  (the  absorbate ) is  dissolved  by or  permeates  a liquid or solid (the  absorbent ), respectively. [2]  Adsorption is a surface-based process while absorption involves the whole volume of the material. The term  sorption encompasses both processes, while  desorption  is the reverse of it. Adsorption is a  surface phenomenon . The nitrogen gas molecules in blue adsorb onto the surface of a carbon nanotube in grey.   ...
