Abstract: The invention relates to a method for detecting trichlorfon and monocrotophos, comprises the steps of molecularly imprinted polymer preparation, molecularly imprinted solid-phase extraction and gas chromatography combination system establishment. The prepared molecularly imprinted polymers with high trichlorfon and monocrotophos selection and recognition performance are used as the adsorption materials, thus the defects of poor selectivity of the traditional adsorbent and the like are overcome. By using the molecularly imprinted solid-phase extraction and the solid-phase chromatography jointly, the rapid and sensitive method can be used for widely detecting a trace amount of trichlorfon and monocrotophos. The method for detecting the trichlorfon and the monocrotophos has low cost, simple experimental operation and high sensitivity and is suitable for rapidly detecting a trace amount of trichlorfon and monocrotophos in various products.
