In this study, a method was developed to detect PFASs in biosolids using high-performance liquid chromatography (HPLC) system coupled with high-resolution mass spectrometer (HRMS). A solid phase extraction (SPE) procedure was applied to extract the PFAS analytes from biosolid samples collected from two local wastewater treatment plants (WWTPs). The SPE procedure under basic conditions showed effective extraction for ionic analytes, with recoveries of 85.62 % and 114.65 % for PFOA and PFOS, respectively. The acidic SPE extraction showed relatively low recoveries for zwitterionic and ionic analytes. Totally 30 analytes were detected in two biosolid samples.
