Abstract: Molecularly imprinted polymers with amobarbital as a template were prepared through bulk polymerization of acrylamide (AM) or methylacrylic acid (MAA) as functional monomers, ethylene glycol dimethacrylate being used as the cross-linking agent and 2,2'-azo-bis-isobutyronitrile as the initiation agent. The discrimination capability and selectivity of the resultant MIPs made from different functional monomers were studied. The acrylamide MIP showed better discrimination capability and selectivity than the MIP from MAA. The adsorption capacity of amobarbital in AM and MAA MIPs was found to be 28.58 μmol/g and 24.77 μmol/g, respectively, these were about 40.9% and 35.9% of the theoretical values.
