摘要
全氟/多氟烷基化合物(PFAS)是一类重要的新污染物,具有生物毒性、环境持久性、生物累积性等特点,可对环境和生物造成一系列危害。因此,实现PFAS的快速灵敏检测至关重要。光学传感因所需设备简单、响应速度快等优点而被广泛用于PFAS的现场快速检测。本文对比色、荧光、表面增强拉曼、共振光散射、表面等离子体共振等多种光学传感检测PFAS的方法进行了综述,详细介绍了各种传感体系的构建和检测机制,并对其传感性能进行了归纳和比较。最后,对PFAS光学传感检测的未来发展趋势和改进方向进行了展望。
Per-/polyfluoroalkyl compounds(PFAS) are an important class of new pollutants with bio-toxic, environmentally persistent, and bio-accumulative, which can cause hazards to organisms and environment.Therefore, realizing rapid and sensitive detection of PFAS is crucial for environmental and human health. Optical sensors are widely used for rapid on-site detection of PFAS due to the advantages of simple equipment and fast response time.In this paper, various optical sensing techniques for the detection of PFAS, such as colorimetry, fluorescence, surface-enhanced Raman spectroscopy, resonance light scattering spectroscopy and surface plasmon resonance spectroscopy, were reviewed. The construction and detection mechanisms of the various sensors were described in detail. The sensing performances were also evaluated and compared. Finally, the future development trend and improvement direction of the optical sensors for PFAS were prospected.
