1.0 INTRODUCTION Adsorption is a separation process which takes advantage of the tendency of one or more components of a liquid or gas to collect on the surface of a solid. This tendency can be leveraged to remove solutes from a liquid or gas or to separate components that have different affinities for the solid.  In adsorption process, adsorbate is known as a substance that accumulates on. . Posted by CHEMYAM: Concepts of Chemistry August 22, 2020. + 0 Online Quiz Class 11. Online Quiz Class 11
