α-Fe2O3and SiO2were prepared from ferric nitrate and TEOS by sol-gel method in combination with using templates. The synthetic samples were characterized by powder X-ray diffraction (XRD) and N2adsorption/desorption methods. We determined the surface acid-base properties of α-Fe2O3/SiO2nano-mixed system by potentiometric titration technique, and studied the adsorption behaviors of heavy metal ions on the solid surface of α-Fe2O3/SiO2nano-mixed system at different pH values. According to the above experimental data, we calculated the surface acid-base reaction equilibrium constants of the nano-mixed system using WinSGW software to be ≡XOH ⇔ ≡XO-+ H+(lg K = -8.19±0.15). The calculated result reveals that the single deprotonation surface of α-Fe2O3/SiO2nano-mixed system is obviously different from the surfaces of α-Fe2O3/SiO2/γ-Al2O3, α-Fe2O3/γ-Al2O3 and SiO2/γ-Al2O3nano-mixed system with surface protonation as well as deprotonation at the same time. Based on the above result, the surface complexation constants of Cu2+, Pb2+, Zn2+on the surface of α-Fe2O3/SiO2mixed systems were simulated respectively as follows:
≡XOH + M2+ ⇔ ≡XOM++ H+ [lg K =-3.1, -3.6, -3.8 (M = Cu, Pb, Zn)].
