Abstract: Novel molecularly imprinted polymers on the surface of poly(vinyl alcohol) modified mutiwalled carbon nanotubes (MWCNTs-MIP) were obtained, which used enrofloxacin as the template molecule, methacrylic acid as the functional monomer, ethylene glycol dimethacrylate as the crosslinking agent and azobisisobutyronitrile as the initiator. The proportion of template molecule, functional monomer and crosslinking agent was studied and the optimum ratio was 1:4:20. The imprinted polymers were characterized by infrared spectroscopy and scanning electron microscopy. The dynamic adsorption experiments demonstrated that MWCNTs-MIP achieves adsorption equilibrium in about 30 min. The static adsorption and Scatchard analysis showed that the MWCNTs-MIP has two adsorption sites, the maximum adsorption amount was 42.3 mg/g, 1.3 times higher than that of the MWCNTs-NIP. Selective experiments indicated that MWCNTs-MIP has a specific recognition performance to enrofloxacin.
