“…Thus, it is of great significance to establish sensitive and simple analytical methods for monitoring and quantitative analysis of residual PCAs in the environmental water samples at trace level. Various analytical technologies, including gas chromatography mass spectrometry (GC-MS) (Suárez et al, 2018), high-performance liquid chromatography (HPLC) (Wu et al, 2005;Mojtaba et al, 2012), liquid chromatography tandem mass spectrometry (LC-MS/MS) (Peng et al, 2018;Ma et al, 2019b;Gao et al, 2014;Jia et al, 2019) and capillary electrophoresis (CE) (Fu et al, 2009), have been used for detecting the amounts of PCAs. Amongst them, LC-MS/MS exhibits the highest sensitivity and accuracy, which is more suitable for the PCAs analysis.…”
