摘要: In the present work, clinoptilolite was magnetized by magnetite nano-powder synthesized chemical co-precipitation route. The clinoptilolite/magnetite nanocomposites were prepared with different weight ratios of 7 : 1, 5 3 1 and using FeCl3 · 6H2O FeCl2 4H2O in an aqueous phase under ambient condition. characterized X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, Fourier transform infrared spectroscopy vibrating sample magnetometer techniques. results characterization suggest that main magnetic nanocomposite is nanoparticle average diameter 18–23 nm saturation magnetization 74.29 emu g–1. specific surface area calculated a BET single-point method as rapid accurate way which can lie almost anywhere on isotherm. values obtained good agreement multiple-point method. It found faster simpler than for routine applications. Also, increasing Fe3O4 content caused increase nanocomposites.
