Method for electrochemical detection of acephate by aid of molecularly imprinted polymer film supported on surface of metal-organic framework material

The invention relates to a method for electrochemical detection of acephate by the aid of a molecularly imprinted polymer film supported on the surface of a metal-organic framework material. The metal-organic framework material formed by cupric nitrate and 4,4'-biphenyldicarboxylic acid is taken as a support body, acephate is taken as a template molecule, methacrylic acid is taken as a function monomer, ethylene glycol dimethacrylate is taken as a crosslinking agent, azodiisobutyronitrile is taken as an initiator, the molecularly imprinted polymer film supported on the surface of the metal-organic framework material is synthesized and ultrasonically dispersed in a nafion solution for spin-coating of the surface of an electrode, and acephate is detected with a differential pulse voltammetry method. A molecularly imprinted polymer with large specific surface area and high mass transfer speed is obtained and is used for detecting acephate. The method has good stability and high sensitivity.
