It was concluded in this study that once the surface excess of the inevitable impurities in the salts is lessened by the introduction of ultrafine gas bubbles, which possess great air/water interfacial area, the Jones-Ray effect becomes nonobservable.

It is shown that the interfacial adsorption and repulsion of small inorganic ions such as H3O+, OH-, HCO3-, and CO32- cannot account for the ζ potential observed in experiments because the surface affinities of these ions are too small.

This model can accurately predict the surface tension of surfactant solutions like sodium dodecyl sulfate (SDS) in the presence of the monovalent salts LiCl, NaCl, KCl, and CsCl and it shows that for SDS, binding of the counterion to both the headgroup and a few CH2 fragments close to the surfactants head contributes to thecounterion-specific effect.

It is shown that the surface potential depends sensitively on both the thickness of the adsorption layer and the interfacial depth at which thesurface potential is probed, and this model provides a much more accurate picture of the surface Potential than classical models.

This work shows that a consistent description of the experimental surface tension of salts, bases, and acids is possible by assuming charged impurities in the water with a surface affinity typical for surfactants, and reveals salt-screening enhanced impurity adsorption as the mechanism behind the Jones-Ray effect.
