摘要: In this research, γ-Fe2O3-β-zeolite nanocomposite was synthesized and functionalized by 3-amino propyl trimethoxysilane. The magnetic adsorbent characterized FTIR, X-ray diffraction, thermal analysis, vibrating sample magnetometry, scattering electron microscopy, N2 adsorption-desorption techniques. then used for adsorption of arsenic from aqueous solutions. At optimized conditions the capacity 30 mg.g−1 obtained, which higher than previously reported values. loaded easily separated solution applying an external field. Regeneration NaOH indicated that 97% initial remained after four adsorption-regeneration cycles.
