The magnetic mesoporous titania/graphene oxide (MTiO2/GO) was synthesized by the materials of graphene oxide (GO), nano-ferroferric oxide and tetrabutyl titanate, through the chemical deposition and hydrothermal method, and was used to treat Cd(Ⅱ)-containing wastewater. MTiO2/GO was characterized by EDS, FTIR and UV-Vis techniques. The effect of GO content in MTiO2/GO, the dosage of MTiO2/GO, the initial pH of solution, the reaction time, and the initial Cd(Ⅱ) concentration on Cd(Ⅱ) adsorption by MTiO2/GO were investigated. The isotherm and kinetics of adsorption were explored. The result showed that MTiO2/GO is a kind of adsorbent with rough surface, large specific surface area and tiny photocatalytic particles on its surface. With GO mass fraction of 60wt%, the pH value of 6, the MTiO2/GO dosage of 10mg and adsorption time of 120 min, the maximum adsorption efficiency of Cd(Ⅱ) by MTiO2/GO was up to 95.43%. The adsorption on Cd(Ⅱ) process can be well described by the pseudo-second order kinetics model and Freundlich isotherm model. The adsorption-desorption experiments showed that the adsorption efficiency of Cd(Ⅱ) remained as high as 91.85% after 5 cycles of adsorption- desorption, indicating the highly circular utilization of MTiO2/GO.
