A new procedure for the derivation of the equation of state in models of adsorption from solution is developed. Based on thermodynamics a simple relation between the surface pressure and the chemical potential of one reference solvent state is established, making the calculation of the state equatio

The Langmuir adsorption equation has become popular for summarizing solution-solid adsorption data and estimating adsorption equilibrium constants. The applicability of the Langmuir equation to estimation of adsorption equilibrium constants at solid-aqueous solution interfaces was theoretically exam
Abstrad-It has been shown that the equation of state for adsorption from solution presented by Nikitas [Electrochim. Acto 32, 1279 (1987)] has, in fact, been derived before in the literature [Karolnak and Mohilner, J. phys. Chem. 86, 2840 (1982)]. Some inconsistencies and pitfalls in the Nikitas der
