Beschreibung
Zusammenfassung:	The invention discloses a preparation method and application of polystyrene-hydroxylated multi-walled carbon nanotube-polypyrrole composite nanofiber. According to the fiber, mixing, dissolving and blending are performed on polystyrene and hydroxylated multi-walled carbon nanotube, and pyrrole monomer is polymerized on the surface of the fiber to obtain the multi-component composite nanofiber. The composite nanofiber as a purification material fills a solid-phase extraction column for pretreatment of organophosphorus pesticide residue detection, and the extraction column can remove most impurities in an agricultural product to achieve the purpose of purification. A detection method comprises the following specific steps of 1, extracting the agricultural product with an organic solvent, and carrying out water removal operation to obtain a to-be-purified solution; 2, performing purifying by the solid-phase extraction column to obtain a to-be-detected solution after the impurities are removed; and 3, performing
