Determination of the ionization and complexation surface reaction constants in the metal oxide/electrolyte system

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