摘要： 采用水热合成法，在X型沸石的晶化原料液中加入磁核合成了磁性沸石，对合成产物进行了结构性能测试. 结果表明，产物为X型沸石结构，具有较好的磁性能和吸附性能. 饱和磁化强度为3.7 emu/g，在磁场作用下，磁性沸石在30 min内完成与母液的分离，产物的比表面积为571.5 m2/g，铅离子吸附量为196.8 mg/g.

Abstract: 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, N2 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 m2/g and the adsorption capacity of Pb2+ about 196.8 mg/g.

Key words: magnetic zeolite, adsorption, lead ion, N2 adsorption-desorption isotherm
