Abstract
Surface charge–pH isotherms for TiO2 in K+, Li+, Mg2+ and tetramethylammonium electrolyte solutions are reported for a TiO2 colloid sample shown previously to be essentially holocrystalline and non-porous. The charge data are similar to other oxides with the exception of precipitated silica. The adsorption sequence obtained is Mg2+ Li+ > K+≃(CH3)4N+.Keywords
