Determination of perfluorinated compounds， antibiotics and pesticides in drinking water by automated solid phase extraction with ultra-performance liquid chromatography-tandem mass spectrometry

Key Points

• The aim is to determine the presence of perfluorinated compounds, antibiotics, and pesticides in drinking water.
• Automated solid phase extraction method for sample preparation.
• Ultra-performance liquid chromatography-tandem mass spectrometry for analysis.
• Assessment of contaminant levels against national standard limits.
• Levels of perfluorooctanoic acid, 2,4-dichlorophenoxyacetic acid, atrazine, carbofuran, and bentazone were below national standard limits.
• Indicated low health risk associated with these compounds in the source water.
• Demonstrated efficiency, rapid processing, and cost-effectiveness of the method for simultaneous determination.
