Since the discovery of multi- walled and single- walled carbon nanotubes (MWNTs and SWNTs, respectively), research ontheir application is being actively carried out. In this report, a series of magnetic Faujasite (FAU) zeolites are hydrothermally synthesized using traditional hydrothermal method by adding empty MWNTs and Fe203- filled MWNTs in the crystallization. The products were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and fourier transform infrared spectroscopy (FTIR> The results show that all the synthesized products exhibit typical nature of FAU zeolites. Comparing the magnetic zeolites (FAU/ Fe203 MWNT) synthesized with pure FAU zeolites, their adsorption capabilities of Cr3+ are still high. When the magnetic zeolites are used to extract ion from solution disposed without molding, their powder products can be easily separated from solvent or solution by magnetic separation technology.
