1.All the molecules in the surface layer react with the adsorbent surface, and all these molecules are in a different state from that of the corresponding molecules in the volume of the solution. Accordingly, in finding the thermodynamic properties of a surface layer the layer must be considered as a whole, i.e., what must be taken into consideration is not the Gibbs (excess) values of the adsorption, but the total concentrations of the components in the adsorbed layer.2.Expressions are obtained for the integral and differential work of adsorption of solutions in terms of the total concentrations of the components in the adsorbed layer.3.Formulas are obtained for calculating the heat of adsorption of a solution from the isosteres of the total content (total concentration) of the components in the adsorbed layer, as well as from the various possible calorimetric measurements. |
