英文摘要A novel composite material of core-shell molecularly imprinted polymers (MIPs) was prepared by surface imprinting technique in combination with sol-gel process based on carbon nanotubes (CNTs) coated with silica. The morphology and structure of the products (CNTs@ Naf-MIPs) were characterized by transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FT-IR). The adsorption properties of CNTs@ Naf-MIPs were demonstrated by equilibrium rebinding experiments and Langmuir analysis. The maximum adsorption capacity and dissociation constant of CNTs@ Naf-MIPs were 9.5 mg/g and 56.6 mL/mg respectively. CNTs@ Naf-MIPs showed a fast kinetics and reached the equilibrium only 30 min. The feasibility of determination of nafcillin from real samples was testified in spiked egg samples with concentration of 5 and 10 mu g/kg by using the imprinted polymer as the adsorption material. The recoveries of nafcillin were ranged from 61.3% to 84.3% with good accuracy.
