Previous studies of the effect of monolayers on the electrical potential difference across polar oil/water interfaces have produced only conflicting data about the existence, magnitude and stability of the so-called adsorption or surface potentials (∆ V ). It is now shown that, with carefully defined experiments, remarkably stable values for ∆ V can often be obtained whose rates of decay are so slow that ∆ V -surface density isotherms similar to those established for air/water or non-polar oil/water interfaces can be obtained. The rapid decays found previously are attributed to inadequate electrical or surface chemical controls.
