Factors Influencing Adsorption from Binary Solutions

3 FACTORS INFLUENCING ADSORPTION FROM BINARY SOLUTIONS 

It has been mentioned earlier that in the case of the adsorption on carbon adsorbents (or any solid adsorbent) from binary solutions, with completely miscible components in all proportions, both the components of the solution are adsorbed although the surface may show preference for one component depending upon the nature of the solid surface and the nature of the two components of the solution. This indicates that there is competition between the two components of the solution (i.e., between the solvent and solute for the adsorbent surface). Thus, the adsorption from binary solutions is now generally called competitive adsorption. Competitive adsorption depends upon several factors, such as the interaction of the soUd surface with the two components of the solution (adsorbate-adsorbent interaction), the interaction between the two components of the solution (adsorbate-adsorbate interaction), the porosity of the solid adsorbent, and the heterogeneity of the adsorbent surface. Furthermore, the assumption that adsorption from solutions at room temperature is
