Abstract: The acrylamide molecularly imprinted polymer was synthesized by using propionamide as a template molecular, methacrylic acid as thefunctional monomer,and ethylene glycol dimethacrylate as the cross-linking agent. The optimal molar ratio of templates to monomers was 1:8.The results of static adsorption equilibrium experiments and scatchard analysis showed; compared with non-imprinted polymer, the imprinted polymer had higher affinity for acrylamide. The max adsorptive capacity was 4.283 mg/g and the dissociation constant (u) was 2.77 g/mL. The infrared spectrum of the polymer indicated that the specific recognition sites in the molecular imprinted polymer were due to the hydrogen bonding effect formed by amide bonds and the carboxyls.
