DETERMINATION OF THE IONIZATION AND COMPLEXATION SURFACE REACTION CONSTANTS IN THE METAL OXIDE/ELECTROLYTE SYSTEM

ABSTRACT

The description of electrical double layer at the metal oxide/electrolyte interface requires the determination of the constants of the ionization and complexation of surface groups. These constants allows to determine distribution of surface charge and a potential across the interface region. The different methods of the estimation of these constants at the metal oxide/electrolyte interface, including potentiometric titration, ion adsorption data and zeta potential are compared.
