What is Diffusion to a Plane with Adsorption According to Frumkin's Isotherm about?

This paper considers the problem of the kinetics of adsorption at the electrode/solution interphase, for a substance which does not undergo chemical or electrochemical reactions. The differential system which describes semi-infinite linear diffusion to a plane has been examined, assuming that at the boundary a generic isotherm holds. In this way one arrives at a Volterra integral equation which in general is non-linear. The numerical solution of such an equation has been carried out for the case of a Frumkin isotherm. The coverage of the electrode$ ,u = F/I',,, as a function of the adimensional quantity log z [= log (C\*s4Df/I'~% )] depends on the parameters PC\* = 'I' and A of the isotherm. The relative graphs allow us to determine the time required to arrive at a fixed coverage. The effects of attractive and repulsive interactions are discussed. ## R&mu&On considere le probleme de la cinetique d'adsorption a l'interphase &ctrodssolution pour une substance qui n'est pas soumise a des reactions chimiques ou &ctrochimiques.
