| titleOfInvention | Method for determining pesticide residue in tea |
| abstract | The invention provides a method for determining pesticide residue in tea. The method comprises the following steps: (1) pretreatment of a sample: a step of crushing tea leaves, dissolving the crushed tea leaves with water, then carrying out ultrasonic extraction with an acetonitrile-acetone solution and then carrying out centrifugation so as to obtain extract liquor; (2) solid phase extraction with a stirring bar: a step of soaking a stirring bar coated with a polymer-graphene coating in the extract liquor and carry out carrying out solid phase extraction; and (3) gas chromatographic-mass chromatographic detection, wherein the pesticide residue is triazole pesticide residue and the polymer-graphene coating on the stirring bar is a cellulose-graphene coating. The method can realize high-efficiency and convenient detection of pesticide residue in tea. |
