Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] A method for detecting carbendazim pesticide residues in fruits and vegetables of the present invention comprises the following steps:

[0023] (1) Sample processing: chop the fruits and vegetables to be tested according to the 4-point method, and then put them in a food mixer and stir them into a paste;

[0024] (2) Oscillation: Weigh 10 g of the sample that has been stirred into a paste with an electronic balance and put it in a 50 mL centrifuge tube. Add ceramic homogenizers to the centrifuge tube. The function of the ceramic homogenizers is to prevent salt agglomeration ; then add 5g of anhydrous sodi...

Abstract

The invention provides a method for detecting carbendazim pesticide residues in fruits and vegetables. The method includes steps of (1) sample treatment, (2) oscillation, (3) centrifugation, (4) concentration, (5) purification, (6) sizing and (7) chromatographic analysis. The method for detecting the carbendazim pesticide residues in the fruits and the vegetables has the advantages that the method is implemented by the aid of ultrahigh-performance liquid chromatographs, accordingly, reagents can be saved, and environmental pollution due to organic reagents can be abated; sample pretreatment is easy to implement and high in accuracy and is speedy, requirements on detecting actual samples can be met by the method with high sensitivity and precision, and the method is applicable to work requirements on quickly detecting carbendazim residues in fruit and vegetable samples in batch and can be used as a conventional method for detecting residues.

Description

technical field [0001] The invention mainly relates to the field of fruit and vegetable detection, in particular to a method for detecting carbendazim pesticide residues in fruits and vegetables. Background technique [0002] Carbendazim, also known as cotton wilting, is a highly efficient and low-toxic systemic insecticide with systemic therapeutic and protective effects. It is a broad-spectrum fungicide and has control effects on various crop diseases caused by fungi. It is used for the prevention and control of diseases of fruit trees, vegetables, grain, cotton and forest trees, especially for the diseases caused by certain pathogenic bacteria and fungi of the class Ascomycetes. At present, the rapid detection kits for pesticide residues in large-scale agricultural wholesale markets are only aimed at the rapid detection of organophosphorus and carbamate pesticides in fruits and vegetables. Therefore, it is imminent to invent a method for fast and accurate detection of ca...
