Abstract

In order to separate ZSM-5 zeolite powders from solution easily, a series of magnetic ZSM-5 zeolites were prepared by hydrothermal synthesis with the addition of magnetic Fe3O4 particles during the crystalline process. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), infrared (IR) spectrum, energy dispersive X-ray (EDX), specific surface area, magnetic susceptibility and adsorption capability. It was found that the magnetic ZSM-5 zeolites had good magnetism and the magnetic susceptibility increased with the increasing amount of Fe3O4 particles. Compared with the pure ZSM-5 zeolite, the adsorption capability of magnetic ZSM-5 zeolites was acceptable. When the magnetic zeolites were used to adsorb Pb2+ from solution, the magnetic zeolite powder could be conveniently separated with magnetic separation technology.
