Abstract

Fe₃O₄@SiO₂@MIL-101(Cr) magnetic porous hybrids were prepared via physical method.The structure and morphology of the resulted samples were characterized by transmission electron microscopy (TEM),X-ray diffraction (XRD), thermogravimetric analysis (TG) and infrared (IR). Through UV absorption spectrum,the influence of adsorption time, concentration of bisphenol A (BPA), and the amounts of Fe₃O₄@SiO₂@MIL-101(Cr).the asorption ability of Fe₃O₄@SiO₂@MIL-101(Cr) for BPA was studied.The results showed that the adsorption ability increased with increasing contact time and the equilibrium was established within 150 min. When the concentration of BPA was 80 mg/L and the amount of magnetic porous materials was 1 mg, the maximum absorption amount was 101.4 mg/g.
