Magnetic zeolite was hydrothermally synthesized with a hydrothermal method by adding magnetic core in the zeolite synthesis system. The products were examined with X-ray diffractometer, transmission electron microscope, vibrating sample magnetometer, N_2 adsorption apparatus, thermogravimetric and differential thermogravimetric instruments. The results show that the magnetic zeolite has an X-type zeolite structure. The product has good magnetic property and adsorption property. The saturation magnetization is about 3.7 emu/g. Magnetic zeolite can be separated from mother liquid by a magnet within 30 min. The BET specific surface area is about 517.5 m~2/g and the adsorption capacity of Pb~(2+) about 196.8 mg/g.
