Notes:
Abstract At sufficiently high concentrations of methanol and of alkali salts in aqueous silica dispersions, the negative ζ-potentials of the particles are decreased. This effect is more pronounced with lithium than with other alkali cations, and it is independent on the anion. The NMR spectra indicate lithium adsorption on silica from mixed solvents, but not in the absence of alcohol.
