Abstract: A series of molecularly imprinted polymers (MIPs) for fomesafen with different template to monomer molar ratios were contrived and developed via precipitation polymerization employing methacrylic acid as functional monomer, ethylene dimethacrylate as crosslinker and acetonitrile as porogen. Binding capacity experiment showed that MIP2 had the highest binding capacity of 3.25 mg g-1 and the best specific affinity with imprinting factor (α) = 1.53. Scatchard isotherm analysis revealed that MIP2 had two affinity sites which had higher recognizability for fomesafen and the apparent maximum adsorption was 16.94 mg g-1. Selectivity analysis indicated that MIP2 could specifically recognize fomesafen from its structure analogues. Morphology and structure of obtained polymers were characterized by scanning electron microscopy and Fourier-transform infrared spectrometry
