Determination of brominated diphenyl ethers in atmospheric particulate matters using selective pressurized liquid extraction and GC-NCI-MS
This study described the development and validation of a sensitive and reliable method for determination of PBDEs in atmospheric particulate matters using selective pressurized liquid extraction(SPLE)and gas chromatography-mass spectrometry with a negative chemical ionization(GC-NCI-MS).Extraction and clean-up were performed using pressurized liquid extraction(PLE)with 2 g florisil and 3 g silica placing in the extraction cells.Under optimal conditions,14 PBDEs were extracted at 70℃ using hexane/dichloromethane(50:50,v/v)as solvent.Validation of SPLE method was evaluated,and excellent recoveries were obtained for most analytes with the RSDs generally below 20%.Method detection limits(MDLs)ranged from 0.13 to 15.38 ng mL-1 for the GC-MS analyses.The method was successfully applied to the atmospheric particulate matters in Beijing,China,where the analytes were detected in the range of 182.79-468.99 pg m-3.
