This procedure covers the quick, cheap, reliable and effective method for extraction and analysis of selected perfluorinated compounds (PFCs) (perfluoroalkyl carboxylates, perfluoroalkyl sulfonates, and fluorotelomer acids) in soil by solvent extraction followed by analysis using liquid chromatography/tandem mass spectrometry. The analytes are extracted with methanol:water (50:50) under basic condition (pH ~ 9-10 adjusted with ammonium hydroxide), filtered, and then acidified with acetic acid (pH ~3-4) and analyzed by liquid chromatography/tandem mass spectrometry.
Standard method for the analysis of PFCs in soils. Land application of biosolids/sludge results in PFC contamination of soils which requires monitoring.
