Abstract:A study of the co-adsorption of cadmium and citrate ions onto the mono-dispersed TiO 2 (anatase)/NaClO 4 aqueous solution interface is presented. The influence of ionic strength and pH on the adsorption of cadmium and citrate ions in this system was investigated. The surface charge density, the ζ-potential and adsorption-edge (or envelope) parameters such as pH 50% and ∆pH 10-90% were also determined for different concentrations of adsorbed ions. The presence of citrate anions increased the adsorption of Cd(II… Show more
