Abstract: The molecularly imprinted polymers (MIPs) were prepared by using bisphenol A (BPA) as atemplate, α-methylacrylic acid as a functional monomer, ethylene glycol dimethyl acrylate as the crosslinking agent, azobisisobutyronitrile as an initiator and toluene as the solvent. Then the static and dynamic experimental results showed that MIPs had specific recognition selectivity and excellent binding selectivity for the template molecule. Scatchard analysis indicated that the bisphenol A imprinted polymer had two kinds of recognition sites with the dissociation constants of 1.36 ml/g and 44.78 m L/g, the apparent maximum adsorption capacities were 24.56 and 312.58 μmol/g, respectively. Besides, in a recovery experiment by adding standard samples into food packaging materials as the sample, the experiment showed that imprinted material of BPA could enrich and separate trace amounts of BPA, and it was also easy to be used repeatedly
