Abstract
The adsorption of sodium polystyrene sulfonate (PSSNa) on TiO2 in aque ous dispersion has been investigated in pure water and in the presence of different concentrations of sodium sulphate. The stability of TiO2 dispersions in PSSNa and Na2SO4 solutions has also been studied. Corr elation between adsorption isotherms, zeta potential data and stabilit y measurements has shown that the specific adorption of sulphate anion s influences the adsorption of PSSNa and then the stability of the dis persions. The adding of propel amounts of Na2SO4 increases the stabili ty of TiO2 dispersions in PSSNa solutions.
