Paper Title:
Some Research on the Magnetic X Zeolite Composites
  Abstract

X zeolite behaves excellent properties of shape selective catalysis, molecular sieves and iron-exchange for its unique tunnel structure and large specific surface area. In this paper magnetic core has been introduced into the zeolite structure and magnetic zeolite with high stability and adsorption properties have been prepared. Synthesis conditions and adsorption of Pb2+ also have been studied. Magnetic zeolite composite was hydrothermally synthesized with a traditional hydrothermal method by adding magnetic Fe3O4 suspension in the zeolite synthesis system. Synthesis conditions and adsorption of Pb2+ also have been studied. The products were characterized with X Ray diffraction (XRD), IR spectrometer (IR), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), Thermogravimetric (TGA) and differential scanning calorimetry (DSC) instruments. The results show that the products have an X zeolite crystal structure and present super paramagnetic properties. The saturation magnetization value of the product is about 3.7 emu•g-1. The weight ratio of magnetic Fe3O4 in the magnetic zeolite composite is calculated to be about 5%. The magnetic zeolite composites have high surface area and the absorption capability of the products is 196.8mg/g.
