摘要
Parameters of the electrical double layer at zirconium silicate/aqueous sodium chloride interface were estimated from potentiometric titrations, background electrolyte ions adsorption and electrophoretic measurements data. Using numerical optimization the ionization and complexation constants of surface hydroxyl groups were determined. The best fit of calculations to the experimental data was achieved by assuming two kinds of surface hydroxyl groups that differ in acid-base properties.
