Abstract A simple steady state model of potentiometric stripping analysis and its derivative mode that are influenced by the film of adsorbed substance that hinders the diffusion of oxidant and metal ions is developed. The dependence of stripping time and the maximum in the derivative mode on the degree of inhibition is calculated. The responses are enhanced if the flux of oxidant is diminished.
