Abstract: Molecularly imprinted polymers with highly selective recognition for acetatilide were prepared by precipitation polymerization using acetaailide as template molecule, methacrylic acid as functional monomer and ethylene glycol dimethaetylate as crosslinker. The experiment 1, measured the influence of the Molar ratio Of the template molecule and the functional monomer upon the adsorption capacity of the I polymers and the optimized ratio was obtained to be n(acetanilide) n(methactylie acid) = 1:4 Scatchard analysis indicated the imprinted polymer acetanilidetemplate molecule and functional Monomer methacrylic acid formed one kind of binding site binding site dissociation constant K-D = 4.35 mmol/L, the apparent rnmdmum binding capacity Q(max) = 111.87 μmol/g
