Sažetak
Surface potential (electrostatic potential at the inner plane of the electrical interfacial layer  0) could be measured by single crystal electrodes. Surface potential is dominantly determined by the binding of ionic species directly to the solid surface. These ions are potential determining ions, i.e. H+ and OH ions in the case of metal oxides. Specific adsorption of organic ions changes the surface potential, which in turn affects their state at the interface i.e. their interfacial activity coefficient. Measurements of surface potential could be used to deduce state of adsorbed organic ionic species at the interface and thus contribute to better understanding of pollution phenomena in the soil. The results with hematite, titania and silica will be presented.
