| titleOfInvention | A kind of detection method of pesticide residues in Prunus chinensis fruit |
| abstract | The present invention provides a method for detecting pesticide residues after pre-treatment of Prunus chinensis fruit by solid-phase extraction and adsorption technology. After soaking in the acetonitrile solution of magnesium sulfate and sodium chloride, the obtained fruit samples were added to the acetonitrile solution of magnesium sulfate and sodium chloride, and then centrifuged to obtain the supernatant; (3) magnesium sulfate and special activated carbon were added to an appropriate amount of the supernatant, and then stirred and filtered; (4) the The filtrate was analyzed for pesticide residues using gas chromatography and mass spectrometry. By adopting the above technical scheme, in the pretreatment process, activated carbon is used to extract and adsorb polar and semi-polar organic acids and pigments in the fruit of P. Analysis of possible damage to the instrument. The method improves detection accuracy, repeatability, and protects analytical instruments. |
