COMPARISON OF ADSORPTION PARAMETERS IN DIFFERENT ISOTHERMS

The objective of this work is to provide a method of interconversion for the isotherm parameters and to propose a unified, rational scale for the standard free energies of adsorption. The authors report adsorption parameters for certain compounds on bismuth which were calculated with the use of different isotherms. The method proposed in this work for expressing the free energies of adsorption calculated via different isotherms proves to be a most appropriate method for obtaining comparable data, since the adsorption energies can be compared under the condition of identical standard states.
