英文摘要: A method for simultaneous determination of PCDDs, dl-PCBs, BFRs and PBDD/Fs in flue gas from stationary source was developed. The sample was extracted by Soxhlet apparatus with toluene, and followed by purification through sulfuric acid partition and multi. layer silica gel column separation. The target compounds were then all separated by passing through the active carbon. dispersed silica gel column and reversal eluting. Gas chromatography coupled with a thermostable capillary column (short length, thin stationary phase film) was operated at pulse injection mode. High resolution mass spectrometry set at low-electron-energy ionization was used for quantification. The high- and low-brominated compounds were determined simultaneously. The detection limits of this method were 0. 081 - 1. 2 pg for PCDD/Fs, 0. 100 - 32 pg for dl-PCBs, 0. 14 - 12 pg for PBDEs, 0. 26 - 16 pg for new BFRs, 0. 44 - 3. 6 pg for tetra- to hepta-BDD/Fs and 8. 2 - 12 pg for OBDD/F. Recoveries (RSDs) in spiked flue gas samples were 88% - 115% (2. 9% - 6. 1%) for PCDD/Fs, 84% - 118% (3. 2% - 10%) for dl-PCBs, 71% - 135% (2. 1% - 18%) for PBDEs, 71% - 114% (2. 9% - 7. 4%) for new BFRs, 83% - 127% (5. 2% - 10%) for tetra- to hepta. BDD/Fs and 52% - 149% (23% - 24%) for OBDD/F. All quality control data fell within the acceptable range specified in analysis standards for flue gas.
