亚硝酸盐有毒并可致癌,是一种广泛存在于自然环境和人类的生活领域中的污染物。亚硝酸盐的快速灵敏检测成为十分必要且具有重要意义的研究工作。电化学方法由于具有反应速度快、灵敏度高、检测限低等优点而倍受青睐。本文从复合电极基底及负载不同活性物质的角度详细介绍了近年来针对亚硝酸盐电化学检测的纳米复合材料传感器的研究进展,重点详述了构建方法和检测结果。以期通过它们个性和共性的比较,对构建新型电化学传感器提供参考。
Nitrite, which is toxic and carcinogenic, is a contaminant widely found in the natural environment and in human life. Rapid and sensitive detection of nitrite becomes a very necessary and important research work. Electrochemical methods due to the reaction speed, high sensitivity, low detection limit and other advantages of much favor. In this paper, the research progress of nanocomposite sensors for electrochemical detection of nitrite has been introduced in detail in the aspects of composite electrode substrates and different active materials loaded, and the construction methods and test results are described in detail. With a view to their reference to the construction of new electrochemical sensors through the comparison of their personality and commonality.
