Abstract

Abstract: The surface acid-base properties of a γ-Al₂O₃/SiO₂ nano-mixed system were studied by potentiometric titration technique. Based on experimental data complemented by surface complexation theory of Constant Capacitance Model, the relevant equilibrium constants of surface acid-base reactions in the nano-mixed system were calculated using the WinSGW program as: ≡XOH+H⁺⇔≡XOH₂⁺ (lgK₁=5.06± 0.05); ≡XOH⇔≡XO^-+H⁺ (lgK₂=-8.45±0.10). Furthermore, the adsorption of heavy metal ions (Cu²⁺ , Pb²⁺ , Zn²⁺ ) at the surface of the γ-Al₂O₃/SiO₂ nano-mixed system was studied as a function of pH. Again using WinSGW software, the surface complexation constants of Cu²⁺, Pb²⁺ and Zn²⁺ ions in aqueous suspensions of γ-Al₂O₃/SiO₂mixed systems were established respectively as: ≡XOH+M²⁺⇔≡XOM⁺+H⁺ [lgK=-2.20, -1.72, -2.90 (M=Cu, Pb, Zn)]

Key words: γ-Al₂O₃/SiO₂ nano-mixed system, Cu²⁺, Pb²⁺, Zn²⁺, Acid-base, Surface complexation, Equilibrium constant
