Adsorption Basics: Part 1 - AIChE

Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the adsorbate (solute )* on the surface of the adsorbent(solvent). This process differs from absorption, in which a fluid (the absorbate) is dissolved by or permeates a liquid or solid … See more The adsorption of gases and solutes is usually described through isotherms, that is, the amount of adsorbate on the adsorbent as a function of its pressure (if gas) or concentration (for liquid phase solutes) at constant … See more Characteristics and general requirements Adsorbents are used usually in the form of spherical pellets, rods, moldings, or monoliths with a hydrodynamic radius between 0.25 and 5 mm.
