摘要

In this work, the tectoridin-imprinted magnetite nanoparticles (TIMNPs) were firstly prepared by using tectoridin as template molecule, methacrylic acid as functional monomer, styrene as crosslinking agent, and superparamagnetic Fe3O4 particles as magnetic component. TIMNPs with a size of about 161 nm were characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), Fourier transform infrared (FT-IR), X-ray diffraction (XRD), vibrating sample magnetometer (VSM), and thermogravimetric analysis (TGA). Rebinding experiments were carried out to determine the specific binding properties and adsorption selectivity. The maximum number of binding sites was 69.58 lmol/g and there was only one kind of binding sites existed in TIMNPs. The relative separation factors for tectoridin with its analogues such as baicalin and atenolol were 2.63 and 2.66, respectively. The results indicated that the synthesized TIMNPs had excellent saturation magnetization, binding capacity, and absorption selectivity. TIMNPs could be one of the most promising candidates for tectoridin extraction. (C) 2016 Wiley Periodicals, Inc.
