Abstract：Fe3 O4@SiO2@MIL -1 01 (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 absorp-tion spectrum,the influence of adsorption time,concentration of bisphenol A (BPA),and the amounts of Fe3 O4@SiO2@MIL -1 01 (Cr).the asorption ability of Fe3 O4@SiO2 @MIL -1 01 (Cr)for BPA was studied. The results showed that the adsorption ability increased with increasing contact time and the equilibrium was established within 1 50 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 1 01 .4 mg/g.
