Abstract: The invention relates to an agitated-film microextraction device and a microextraction method, which are mainly used to separate and enrich target substance in complex aqueous solution sample and belong to the technical field of analyzed chemical sample preprocessing. The agitated-film microextraction device comprises a magnetic clip and a porous film envelop, molecularly imprinted polymer is loaded in the porous film envelop, and the porous film envelop is fixed on the magnetic clip. In the process of extraction, after being impregnated in organic solvent, the porous film envelop is fixed on the magnetic clip, and is put into sample solution and agitated, and the target substance in the sample passes through the organic phase-impregnated porous film to reach the organic phase in the film, and is selectively adsorbed on the molecularly imprinted polymer.; The microextraction device has the advantages of simple preparation, low cost, convenient use, high enrichment factor, good selectivity and repetitive use, and can be used to separate and enrich target substance in complex aqueous solution sample.
