METHOD FOR DETECTING PESTICIDE RESIDUES IN AGRICULTURAL PRODUCTS

The present invention discloses a method for detecting pesticide residues in agricultural products, comprising the following steps: step (1) Establishing a detection model: (1.1) Preparing a sample: (1.2) Collecting spectral data; (1.3) Establishing a detection model; step (2) Detecting the spectrum of agricultural products: (2.1) Sample preparation: (2.2) Sample processing: take the solute prepared above and dissolve it in 75ml alcohol solution; (2.3) Collect spectral data: obtain the near-infrared transmission spectrum of the solute solution dissolved in alcohol; (3) Determine the composition and content of pesticides in agricultural products; compare the near-infrared transmission spectrum of the dissolved alcohol solute solution obtained in step (2.3) with the spectrum and the pesticide content detection model obtained in step (1.3). The invention realizes the precise detection of the types and contents of pesticides, and the improvement of the detection device makes the sample preparation refined, which greatly improves the selective permeability of pesticide molecules, thereby improving the accuracy of measurement and meeting the actual requirements.
