Problems solved by technology

However, there is a strong π-π bond between graphene sheets, which affects its dispersion in solution, that is, it is prone to coagulation in solution, which affects the sensitivity of graphene oxide as an electrode sensor. Then reduce the detection accuracy and detection sensitivity of the detection substances, especially for the detection of toxic substances such as carbendazim, which requires higher sensitivity, and then under the premise of improving the detection accuracy, it is necessary to oxidize the above-mentioned The electrode of the sensor prepared by graphene is modified to improve the accuracy of electrochemical detection of carbendazim

Description

technical field [0001] The invention relates to the technical field of electrochemical sensors, in particular to a throwable trace carbendazim screen-printed electrochemical sensor and a preparation method and application thereof. Background technique [0002] Carbendazim, also known as N-2-phenylpropazolyl carbamate methyl ester, abbreviated as BCM, its molecular formula is C 9 h 9 N 3 o 2 . BCM is a broad-spectrum, high-efficiency, low-toxicity, systemic fungicide with systemic therapeutic and protective effects. It has a control effect on many kinds of crop diseases caused by fungi, and is widely used in the treatment of crops and other diseases. Because of its relatively long residual effect period, it is toxic to mammals and humans, and it will also cause pollution and harm to the environment. , therefore, the detection of carbendazim is crucial. There are many methods for detecting carbendazim, among which the common ones are: enzyme-linked immunoassay, ultraviol...
