Abstract: A novel composite imprinted material based on multi-wall carbon nanotubes (MWNT) was synthesized successfully with a surface polymerization method using benzoyl peroxide (BPO) as a template molecule, methacrylic acid (MAA) as functional monomers, ethylene glycol dimethacrylate (EGDMA) as cross-linkers. The molecularly imprinted polymers (MIP) based on the surface of MWNT was characterized by infrared spectroscopy (IR), differential thermal analysis (DTA) and scanning electron microscopy (SEM), and the results suggested that MIP was grafted to the surface of MWNT successfully. The adsorption amount of benzoyl peroxide by MIP was measured by high performance liquid chromatography (HPLC) and equilibrium binding experiment. A kind of binding site was observed for MIP to BPO with the maximum apparent binding constant of 56.20 mu mol/g. Being used as solid-phase extraction materials, the imprinted polymers extracted benzoyl peroxide from flour successfully with the concentration enrichment factor of 526
