Pitfalls of the phase-shift method for determining adsorption isotherms
Pitfalls of the phase-shift method for determining adsorption isotherms in the case of two-step Faradaic reactions involving adsorption at transition metals (alloys)/aqueous solution interfaces are discussed following the recent publication of the paper [J.Y. Chun, J.H. Chun, Electrochem. Commun., 11(2009)744]. It is shown how the pitfalls of the method are generated by improper analysis of impedance data resulting in at least disputable values characterizing adsorption isotherms (equilibrium constant, K, standard free energy, and interaction parameter between adsorbed species, g).
