| Popis: | Perfluoroalkyl substances (PFAS) are known as highly fluorinated aliphatic compounds that are used in a wide variety of industrial and consumer products causing devastating effects on human health and environment. Wastewater treatment plants (WWTPs) have been suggested to be a point source for PFAS to the environment due to emission of effluent and sludge. In this study, an analytical method was established and validated for the analysis of 16 PFAS in environmental samples (seawater, lake and wastewater) and bi-distilled water. All samples were filtered after collection and extracted/purified/pre-concentrated by a weak-anion exchange solid-phase extraction (SPE) procedure. Ultra performance liquid chromatography (UPLC) coupled to Orbitrap mass spectrometry (Orbitrap-MS) employing electrospray ionization (ESI) interface operated in negative mode was used for the quantitative determination of these contaminants. The method was validated in all aqueous matrices with very good linearity (R2 > 0.99), recoveries (60–110%, for most of the compounds), detection/quantification limits (at ng L−1 scale), process efficiency (43%–119%), expanded measured uncertainty ( |
