Abstract: Precipitation polymerization was used to prepare molecular imprinted polymers (MIPs) of chloramphenicol. using chloramphenicol as template molecular, MAA as the functional monomer, ethylene glycol dimethacrylate as the cross-linker (chloramphenicol:MAA:ethylene glycol dimethacrylate was 1:4:20 (mole ratio)), acetonitrile-water system as the porogenic solvent, and 2, 2'-Azobisiso butyronitrile as the initiator, chloramphenicol molecular imprinted polymer microspheres with an average size of 13.83 μm were synthesized with water bathing at 60 °C and stirring at the speed of 400 r min-1. The product showed a maximum adsorption of 85 μmol g-1 for chloramphenicol. Linear equation was obtained by Scatchard analysis, which illustrated that there were homogeneous selectivity adsorption sites on the surface of MIPs and its maximum apparent adsorption was 529.42 μmol g-1.
