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. |
