Abstract: Two amino acids magnetic molecularly imprinted polymers, Ala-MMIPs and Phe-MMIPs were prepared by using Ala and Phe as template molecules, styrene and methacrylic acid as functional monomers, divinylbenzene as cross-linking agent and Fe3O4 as magnetic fluid. Adsorption properties of these two imprinted polymers were researched. Adsorption mechanism was also discussed. The maximum adsorption capacity (qmax) and the adsorption equilibrium constant (K) of Phe on Phe-MMIPs were 231.62 μmol/g and 0.21 L/mmol respectively. The maximum adsorption capacity and the adsorption equilibrium constant of Ala on Ala-MMIPs were 179.16 μmol/g and 0.12 L/mmol respectively. The results exhibit that three-site interaction between Phe and Phe-MMIPs was stronger than the two-site interaction between Ala and Ala-MMIPs
