| Abstract: |
| A gas chromatography-mass spectrometric（GC-MS） method was developed for the simultaneous determination of polybrominated biphenyl（PBBs） and polybrominated biphenyl ethers（PBDEs） in pressure-sensitive adhesive and its products.The sample was dissolved with ethyl acetate，and then precipited with methanol to remove polymer.The extract was centrifugally separated for 5 min at a speed of 3 000 r/min，and analyzed by GC-MS under the selected ion monitoring mode.The method showed good linearities in the range of 0.1-10 mg/L for PBBs and PBDEs,with correlation coefficients not less than 0.999.The spiked recoveries were in the range of 86.5%-99.7% for PBBs with relative standard deviations（RSDs） less than 7%，and 91.4%-95.8% for PBDEs with RSDs less than 5%.The method was simple，sensitive and repeatable，and could meet the requirements for the determination of PBBs and PBDEs in the pressure-sensitive adhesive and its products. |
