Thiacloprid and acetamiprid are widely used insecticides, but their potential risks to human health and environmental safety caused by residual amounts have attracted widespread attention for a long time. Therefore, it is very necessary to establish an efficient, accurate, and sensitive quantitative analysis method for the detection of thiacloprid and acetamiprid residues.In this project, 14 common agricultural product samples including vegetables, fruits, grains, and tea will be collected. The sample pretreatment will adopt ultrasonic extraction technology, and the clean extract will be obtained for UPLC analysis. In the analysis process, ABI 4000 QTRAP triple quadrupole mass spectrometer combined with UPLC will be 精品文档---下载后可任意编辑selected for qualitative and quantitative analysis. At the same time, the internal standard method will be used to calibrate the recovery rate of the standard sample. Establish standard curve, test the reliability and sensitivity of the method.Finally, after optimizing the experimental parameters, the optimal analysis method will be established. Based on this, the determination and analysis of thiacloprid and acetamiprid residues in 14 types of agricultural products will be carried out respectively to confirm whether they exceed the national relevant standards.【Key Words】thiacloprid, acetamiprid, residue, ultrasonic extraction, UPLC-MS/MS
