| Abstract: |
| A pyrolysis/gas chromatography－mass spectrometry was established for the determination of alternative brominated flame retardants?（ABFRs） in recycled styrene polymers in this paper．And the pyrolysis and chromatography－mass spectrometry conditions were optimized．Samples were crushed into small particles in advance．The 13 ABFRs were pyrolyzed out of polymers by programmed heating in the pyrolysis furnace，then separated on a ZB－5HT INFERNO column（15 m × 0.25 mm × 0.10 μm），and determined by mass spectrometry under selected ion monitoring（SIM） mode．There were linear relationships for the analytes in the range of 10－500 mg/kg，with limits of quantitation between 3.2 mg/kg and 10.5 mg/kg．The recoveries ranged from 85.3% to 114%，with relative standard deviations（RSDs，n = 6） not more than 16%．This method was rapid，precise and convenient to operate，and was appropriate for the determination of ABFRs in recycled styrene polymers． |
