Abstract
The approach is demonstrated using results for dispersions consisted of SiO2 colloids in 20Â mM NaCl and 100Â mM KCl electrolyte solutions with a pH between â¼9 and â¼2. The work has shown that the surface charge density determined by XPS is in good agreement with potentiometric titration experiments in the pH interval investigated, where the former technique may provide constraints for determining unambiguously the absolute surface charge density.
