Abstract

The invention discloses an electrochemiluminescence sensor for detecting trace pesticide residue and a method for detecting pesticide residue. An electrode preparation method (figure attached) comprises the following steps: selecting an identifier of the pesticide residue; preparing quantum dots and graphene nano material according to documents; and modifying the nano material, the quantum dots and the identifier onto the electrode surface of the sensor by the electrode surface modification technology. The method for detecting the trace pesticide residue comprises the following steps: connecting the modified electrode to an electrochemiluminescence instrument and detecting the pesticide residue in the sample extract. The electrode in the invention has high specificity and sensitivity capable of reaching ng level, a basic detection process is finished only within 3-5 min, and the cost is low. The method for detecting the pesticide residue by utilizing the electrode is fast and simple to operate, and the reaction is automatically finished and the result is automatically recorded by an apparatus.

Description

technical field

[0001] The invention relates to the technical field of pesticide residue detection, more specifically to the preparation of an electrochemiluminescence sensor for detecting trace pesticide residues, and the invention also relates to the use of the electrochemiluminescence sensor to detect traces in agricultural product samples. methods for measuring pesticide residues. Background technique

[0002] Pesticide residues mainly include insecticides, fungicides, herbicides, etc. according to different uses of pesticides. Pesticide residues interfere with the normal behavior of organisms and the synthesis, storage, secretion, transport, combination, and clearance of normal hormones related to reproduction and development.

[0003] At present, pesticide residues have become a new generation of environmental pollutants and food pollutants that urgently need to be treated. A small amount of pesticide residues can affect normal hormones, interfere with endocrine funct...
