In this paper, an experimental study of the adsorption of potential-determining ions at the zincite (ZnO) aqueous solution interface is reported, where changes in solubility of the oxide with pH are shown to limit adsorptive measurements to the pH range 8-10.
Abstract
An experimental study of the adsorption of potential-determining ions at the zincite (ZnO) aqueous solution interface is reported. Changes in solubility of the oxide with pH are shown to limit adsorption measurements to the pH range 8–10. The pzc of ZnO, as determined by the intersection of adsorption curves at low ionic strength, is shown to depend on the method of preparation and on the nature of the supporting electrolyte.

Surface ionization and complexation at the oxide/water interface

TL;DR: In this article, a method for determination of intrinsic ionization and complexation constants of oxide surface sites from potentiometric titration data is reported using these experimental properties and the stoichiometry of surface reactions, surface charge, σo, adsorption density, Γi, and diffuse layer potentials, ψd, at the oxide/water interface.

The surface chemistry of hydrous manganese dioxide

TL;DR: An experimental investigation has shown that H+ and OH− are potential determining ions for the δMnO2 surface The pH (ZPC) was determined using electrophoretic mobilities and Na+ and K+ adsorption and found to be 225 Alkalimetric titration curves failed to provide a direct determination of the pH as mentioned in this paper.

Phosphate glass dissolution in aqueous solutions

TL;DR: In this article, a series of phosphate glasses having the composition (50 − X)M2O·(X)CaO·50P2O5 were monitored using pH stat titration techniques, solution analyses using inductively coupled plasma emission, and depth profiling of corroded glass surfaces for H and other elements using elastic recoil detection analysis and Rutherford backscattering.
