Abstract
In order to facilitate analysis of potentiometric titration data on colloidal TiO2 dispersions, a detailed gas adsorption and tritium exchange study of the TiO2 colloidal material has been undertaken. Gas adsorption data revealed no significant porosity. The weight loss and tritium exchange yield the number of surface protons as 12.5 nm–2, which is consistent with the crystal being made up of exposed crystal planes. This concordance substantiates the essential non-porosity and absence of a gel layer at the TiO2–water interface.Keywords
