Abstract:

Nitrite is an indispensable part of the environment and the biological cycle, but excessive concentrations of nitrite not only pollute the environment, but also cause cancer. Therefore, it is of scientific and practical significance to realize efficient and rapid determination of nitrite. The analysis and determination of contaminants based on electrochemical sensing technology have become a research hotspot. In particular, the selection and design of working electrodes are very important for the researchers to improve the response speed, sensitivity, detection limit, reduce the cost and simplify the operation attention. For the detection of nitrite, this paper reviews the research progress of electrochemical sensors based on different electrodes including the glassy carbon electrode, carbon paste electrode, metal film, polymer film and carbon cloth electrode. Through the construction method and the comparison of electrocatalytic performance, the authors hope to provide a theoretical and practical guidance for the construction of new sensors.
