A comprehensive analytical method based on liquid chromatography tandem mass spectrometry has been developed for the determination of nonylphenol, octylphenol and bisphenol A in textiles and food packaging) materials. Various textile and food packaging material samples were extracted under the conditions of 10.3 MPa and 120 ℃ by accelerated solvent extraction method with two static cycles using ethanol as the extraction) solvent. The extract was cleaned up by Supelclean Envi-Carb solid phase extraction cartridge. Qualitative) and quantitative analyses were carried out for the analytes under the multiple reaction monitoring(MRM) mode after the chromatographic separation on Waters XBridge C_(18))(150 mm×2.1 mm, 3.5 μm) column) with methanol-0.1% NH_4OH gradient elution. The limits of detection(LODs) for alkylphenol, octyphenol and bisphenol A were 0.5 μg/kg. The mean recoveries for textile samples at the spiked level of 0.5-10 μg/kg were 86.9%-92.5%, with the relative standard deviation less than 9.1%. The mean recoveries for food packaging material samples at the spiked level of 0.5-10 μg/kg were 87.8%-93.0%, with the relative standard deviation less than 8.8%. The method is accurate, simple, rapid, and adapts to the inspection of nonylphenol, octylphenol and bisphenol A in textiles and food packaging materials.
