摘要
An analytical model for surface charge density and zeta potential of silica particles is derived and verified. The model takes into account surface chemistry reactions of the silanol groups and multiple ionic species. The predictions are in good agreement with the experimental data available from the literature. Surface charge density and zeta potential of silica particles strongly depend on both pH and background salt concentration of the aqueous solution.
