Research progress on sensing methods for the detection of perfluorinated compounds in water environment

全氟化合物(PFCs)作为一类新型的持久性有机污染物,可以对环境和人体健康造成巨大的危害效应.尤其在水环境中PFCs污染较为严重,污染分布范围广泛,使饮用水安全存在较大风险.建立有效的分析方法对水环境中的PFCs污染水平进行及时检测是非常必要的.虽然采用色谱-质谱联用技术已经实现了对PFCs的高灵敏检测,但是检测周期较长,检测成本较高.为了解决该问题,近年来,电化学和光学传感方法逐渐被研究用于水环境中PFCs的检测.传感方法可以提高对PFCs检测的便捷性,降低检测成本,并具有现场检测的应用潜力.本文主要对电化学和光学传感方法在PFCs检测中的研究进展进行了综述,并对未来的研究趋势进行了预测和展望,希望可为水环境中PFCs的快速检测技术研究提供参考.

As a new type of persistent organic pollutants,perfluorinated compounds(PFCs)can cause great harm to the environment and human health.Especially,the pollution of PFCs is more serious in water environment,which is widely distributed and makes a great risk to the safety of drinking water.It is very necessary to establish the effective analytical methods to detect the pollution level of PFCs in water environment in time.Although the highly sensitive detection of PFCs has been realized by chromatography-mass spectrometry,it takes a long time and high cost.To solve this problem,electrochemical and optical sensing methods have been gradually investigated for the detection of PFCs in water environment in recent years.Sensing methods can improve the convenience of detection of PFCs,reduce the detection cost,and have the application potential of on-site detection.In this review,we mainly summarize the research progress of electrochemical and optical sensing methods in the detection of PFCs,and forecast and prospect the future research trends,which can provide a reference for the rapid detection technology research of PFCs in water environment.
