Abstract: A core-shell multiwall carbon nanotubes-molecularly imprinted polymers (MIPs) composite for chloramphenicols (CAP) (MWCNTs@CAP-MIPs) was prepared by surface molecular imprinting technique using3-aminopropyltriethoxysilane (APTES) and phenyltrimethoxysilane (PTMOS) as functional monomer, tetraethoxysilicane (TEOS)as cross-linking agent. The morphology and structure of the imprinted composite were characterized by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA). The adsorption properties of the polymers were valued by equilibrium rebinding experiments and Langmuir analysis. The MWCNTs@CAP-MIPs showed fast kinetics, high capacity and favorable selectivity, and the imprinting factor (IF) reached to 4.2. The feasibility of determination of CAP from real samples was testified in spiked egg samples using MWCNTs@CAP-MIPs as the adsorbents. The recoveries of spiked CAP were ranged from 72.4% to 84.1%.
