| Abstract: | A gas chromatography-mass spectrometric(GC-MS) method was established for the rapid determination of total polychlorinated biphenyls(PCBs) in soil and sediment.The sample was extracted by accelerated solvent extraction(ASE),and cleaned up with Bond ElutPCB solid phase extraction column.The analysis of PCBs was performed with GC-MS.The calibration curves of PCBs were linear in the investigated concentration range with correlation coefficients of 0.997-0.998.The average recoveries of each kind of chlorinated ... |
