摘要: Abstract A novel electrochemical sensor based on molecularly imprinted polymer (MIP) and iron metal-organic frameworks was fabricated for highly sensitive detection of melamine (MEL) in this work. MIL-53(Fe), a kind frameworks, prepared by simple solvothermal method. The films with specific recognition sites were synthesized electropolymerization using methacrylic acid (MAA) as functional monomers interacted MEL templates. MIL-53(Fe) characterized XRD FT-IR. morphology the MIP modified electrode scanning electron microscopy. Under optimal conditions, (MIECS) shows wide linear range 10−11 M to 10−6 M limit (3σ) low 8.21 × 10−12 M. Moreover, high selectivity melamine, good reproducibility stability. MIECS has been applied real liquid milk samples satisfying results.
