Detection Technology and Pretreatment Methods of Per-and Polyfluoroalkyl Substances
Per-and polyfluoroalkyl substances(PFASs)are chemically inert and hydrophobic and oleophobic,and are widely used in many fields.These characteristics also mean that PFASs are difficult to degrade after entering the environment,and some PFASs have certain biological toxicity.In this paper,the pretreatment methods and detection techniques of PFASs-related samples are reviewed,and the future research directions are prospected.
