Determination of Chlorinated-and Brominated-Polycyclic Aromatic Hydrocarbons in Soil Samples by Gas Chromatography Coupled with Triple Quadrupole Mass Spectrometry


Abstract:
In this study, simultaneous determination of Cl-PAHs and Br-PAHs was developed by gas chromatography coupled to triple quadrupole mass spectrometry (GC-QQQ-MS/MS). Soil samples were exacted and cleaned through silica gel column, dual-layer carbon reversible column respectively, after that, 19 congeners of Cl-PAHs and 8 congeners of Br-PAHs were quantified. The GC-QQQ-MS/MS analysis condition was: EI and Multi-reaction monitoring(MRM) model, the electron emission energy was 70 eV; DB-5 MS fused silica capillary column (60 m ×0.25 mm, 0.25 μm); the temperatures of injection, ion source, quadrupole and transfer line were 280, 230, 150 and 300℃, respectively. The collision and quenching flow were 1.5 and 2.25 mL/min, respectively. The carrier gas was Helium with the flow 1.0 mL/min. The results showed that the relative standard deviation (RSD) of parallel standard reference sample were ≤12.0%, and the recoveries of d-PAHs, Cl-PAHs and Br-PAHs were between 70%-118%. The instrument detection limits of Cl-PAHs and Br-PAHs were between 0.4-5.0 pg. Concentrations of ∑Cl-PAHs and ∑Br-PAHs in the soil samples from a certain industrial area were in the range of 725-1012 pg/g and 353-5924 pg/g, respectively.
