| titleOfInvention | Rapid and accurate detection method for pesticide residue in agricultural products |
| abstract | The invention discloses a method for rapidly and accurately detecting pesticide residue in agricultural products, which is characterized in that the surface of ferroferric oxide is modified to obtain magnetic nanoparticles, trace substances in a sample can be selectively absorbed, then the magnetic nanoparticles are further separated, a target substance to be detected is eluted by adopting a proper elution solvent, and the solid-liquid separation can be carried out by only one magnet. The method comprises the following steps: s1, grinding by using a colloid mill; s2, shaking and mixing; s3, placing the magnet on the side wall of the centrifuge tube with the plug for adsorption; s4, carrying out ultrasonic elution on the magnetic nanoparticles in the centrifuge tube with the plug by using an organic solvent, and carrying out nitrogen blowing concentration to obtain a solution to be detected; and S5, adding a quantitative internal standard into the liquid to be detected, and analyzing by using a GC/MS instrument. |
