| description | The magnetic functionalized graphene based 17β-estradiol molecularly imprinted composite membrane (GO@Fe<sub>3</sub>O<sub>4</sub>-MIP) was successfully prepared by reversible addition fragmentation chain transfer (RAFT) polymerization technique using GO@Fe<sub>3</sub>O<sub>4</sub> as carrier and 17β-estradiol as template molecule. High resolution transmission electron microscopy (HRTEM) and atomic force microscope(AFM), vibrating sample magnetometer(VSM) were employed to characterize the as-prepared samples. The results show that the calculated magnetic property of GO@Fe<sub>3</sub>O<sub>4</sub>-MIP is 12.89 A·m<sup>2</sup>·kg<sup>-1</sup> and the thickness is about 6.45 nm. The adsorption equilibrium time of GO@Fe<sub>3</sub>O<sub>4</sub>-MIP on 17β-estradiol is 30 min, the maximum adsorption capacity is 28.62 mg/g. These findings confirm that GO@Fe<sub>3</sub>O<sub>4</sub>-MIP has high adsorption efficiency and good adsorption selectivity for 17β-estradiol. |
