The invention relates to a method for determining fluensulfone in plant-derived food. The method is characterized by comprising the following steps of: ultrasonically extracting a sample in a special extraction tube by using acetonitrile, purifying in situ by using a niobium carbide nanosheet, then performing filtering, and determining the residual quantity of fluensulfone in an extracting solution by using ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The method provided by the invention overcomes the defects of a sample treatment method in the prior art, fills the blank of determination of the substances, and can provide many references for determination of related pesticide residues and development of methods and technologies; and compared with the prior art, the method has the advantages that the sample pretreatment process is simple and rapid, extraction and purification are integrated, and the method has the advantages of being accurate in operation, high in sensiti
