Liquid-Phase Adsorption is the adhesion of atoms, ions, or molecules from a liquid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent.
Liquid-phase adsorption processes are important in the removal of organic contaminant from waste water it involves the liquid-phase adsorption of an organic compound from aqueous solution on solid support.
If the liquid is a homogeneous binary mixture, it is customary to designate one component as the solute (A) and the other as the solvent (B).
The assumption is then made that the change in concentration of the liquid mixture in contact with a solid adsorbent is due entirely to the adsorption of the solute. The solvent is assumed to be non-adsorbed.
