Abstract: The invention relates to the technical field of safety detection of foods and particularly relates to an acetamiprid molecularly-imprinted solid-phase extraction column as well as a preparation methodand application thereof. The acetamiprid molecularly-imprinted solid-phase extraction column is used for polymerizing acetamiprid as a template molecule, methacrylic acid as a functional monomer, ethylene glycol dimethacrylate as a cross-linking agent and azodiisobutyronitrile as an initiator to form an acetamiprid molecularly-imprinted polymer, eluting and drying the acetamiprid molecularly-imprinted polymer, then filling the acetamiprid molecularly-imprinted polymer with the solid-phase extraction column of a polyacrylic cover as a filler. According to the acetamiprid molecularly-imprintedsolid-phase extraction column as well as the preparation method and application thereof, the acetamiprid molecularly-imprinted solid-phase extraction column is capable of specifically adsorbing and separating acetamiprid molecules, has specificity, and is extremely suitable for collecting, gathering and analyzing the acetamiprid molecules in complex sample matrixes; a method for rapidly, sensitively and conveniently detecting the acetamiprid in the foods is established.
