Abstract

Magnetically modified Fe-Al pillared bentonite (Fe₃O₄/Fe-Al-Bent) was prepared via chemical co-precipitation method and characterized by powder X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). A series of experiments were carried out to investigate the degradation of Orange II by the obtained heterogeneous catalysts in the presence of H₂O₂. The experimental result indicated that the synthetic materials had a high catalytic activity and good reusability.
