Abstract: The molecularly imprinted polymer ( MIPs) were prepared by bulk polymerization using phytic acid ( PA) as template molecule, MAA as functional monomer, N, N'-Ethylenebis ( acrylamide) as crosslinker, Ammonium persulphate as initiator.Surface structure of molecularly imprinted polymers was observed by SEM, the chemical structure of MIPs was characterized by FT-IR. MIPs adsorption performance were investigated by dynamic adsorption, static adsorption and selective adsorption experiments. The experimental results showed that the PA MIPs exhibited good adsorption and recognition abilities, with imprinted factors of 1.70, while myo-inositol ( MI) was 1.46.The adsorption reaction reached equilibrium after 80 min, and the desorption ratio of ractopamine reached 89.59%.The experimental results showed that MIPs not only have specific recognition selectivity, but also have good desorption property for PA, and the adsorption capacity of phytic acid was 21.38 μmol·g^-1.After adsorption-desorption 5 times, MIPs were stable and reusable, the adsorption capacity of phytic acid was 65.62 μmol·g^-1, which was 90.00% of the first adsorption capacity and could be cycle used.
