Dispersion and Solid State Ion Exchange of VCl_3, CrCl_3·6H_2O, MnCl_2·4H_2O and CoCl_2·6H_2O onto the Surface of NaY Zeolite Using Microwave Irradiation

摘要

Transition metal/Y zeolites have been prepared by solid state ion exchange with microwave irradiation of mechanical mixtures of VCl_3, CrCl_3 · 6H_2O, MnCl_2 · 4H_2O or CoCl_2 · 6H_2O with NaY zeolite at 900 W in 10-20 min. The prepared transition metal/Y zeolites were characterized by X-ray diffraction (XRD), infrared spectroscopy (IR), simultaneous thermal analysis (STA) and surface area measurement (BET). Concentration of dispersed transition metal on zeolite was measured and results revealed that transition metal was dispersed and ion exchanged onto the surface of NaY zeolite.
