Research Progress on Pre-treatment and Detection Methods of Polycyclic Aromatic Hydrocarbons in Water
At present,commonly used pre-treatment methods for Polycyclic Aromatic Hydrocarbons(PAHs)in water include liquid-liquid extraction,solid-phase extraction,solid-phase microextraction,and dispersed liquid-liquid microextraction,and detection methods include capillary electrophoresis,gas chromatography,high-performance liquid chromatography,gas chromatography-mass spectrometry,liquid chromatography-mass spectrometry,and surface enhanced Raman spectroscopy.This paper reviews the commonly used pre-treatment and detection methods for PAHs in water,and then looks forward to their development trends to improve the detection efficiency of PAHs in water and provide data support for regional water environment improvement.
