【 摘 要 】

Sodalite/Magnetite was efficiently fabricated by a one-step hydrothermal route using natural tourmaline as a silicon-aluminum source. The obtained products were characterized by X-ray diffraction, field emission scanning electron microscope, and elemental analysis (ICP) and N2 adsorption-desorption isotherm. In addition, the adsorption characteristics of metal ions (Cu2+, Co2+, Cr3+) on the sodalite were investigated. The results show that sodalite covered by octahedral particles of Fe3O4 was successfully obtained under hydrothermal treatment temperature at 300 °C. Nitrogen adsorption studies of sodalities showed the pore size around 0.7 nm and BET surface area over 0.315 m2/g. The adsorption capacities of Cu2+, Co2+and Cr3+ on sodalite/magnetite were 25.95, 8.90 and 4.1 mg/g.
