Abstract: Isotherms and enthalpies of multicomponent adsorbates with load-dependent adsorption energies, being formed on adsorbates with fractal surfaces (2⩽D⩽3) and being in equilibrium with either real fluid- or ideal gas-adsorptives, are given. The functions proposed are solutions of a set of Maxwell's relations and other thermodynamic consistency conditions. Special cases of the general expressions given are discussed to a certain extent, among them generalizations of the Langmuir-Freundlich and the BET adsorption isotherms.
