Research progress on the application of nanomaterials in electrochemical detection of nitrite
Nitrite,as a common food additive,can stabilize the color,enhance flavor,and extend shelf life of meat products.However,nitrite is also a toxic pollutant,and long-term excessive intake will seriously endanger human health.Therefore,achieving high sensitivity and selectivity for its rapid detection is of great significance.Compared with other traditional detection methods,electrochemical detection has the advantages of simple operation,good selectivity,and high sensitivity.As the core component of electrochemical sensors,electrode materials will have an impact on the overall performance of the sensor in terms of their functionality and interface performance.This article provides a detailed introduction to the research progress of nanocomposites such as carbon,metals,metal oxides,and conductive polymers in the electrochemical detection of nitrite.The construction methods and detection results are emphasized,and the future development trends of nitrite sensors are discussed.
