摘要：
Fe3O4 magnetic nanoparticles were synthesized by the chemical co-precipitation method. With (3-aminopropyl)triethoxysilane (APTES) on the surface modification, Fe3O4@SiO2-NH2 nanoparticles were formed. Core-shell magnetic molecularly imprinted polymers (Fe3O4@MIPs) were prepared by using Rhodamine 6G as template molecule, acrylamide (AM) as functional monomer, trimethylolpropane trimethacrylate (TRIM) as cross-linking agent, and amino-modified Fe3O4 magnetic nanoparticles as the magnetic core. The Fe3O4@MIPs were characterized using a Fourier transform infrared spectrometer(FT-IR), field emission scanning electron microscope (FESEM), vibrating sample magnetometer(VSM), and thermogravimetric analysis (TGA). The Fe3O4@MIPs showed a highly improved imprinting capacity and significant selective; they could be used as solid-phase extraction material and applied to the safety detection of illegal add Rhodamine 6G in foods. ©, 2014, Journal of Functional Materials.
