| Abstract: |
| A method for determining 19 polychlorinated biphenyl compounds in sediment was established by Soxhlet extraction and GC/MS/MS.The optimal mass spectrometry condition of the multiple reaction monitoring (MRM) modes for 19 polychlorinated biphenyl compounds was determined.The lower limits of determination were between 0.020μg/kg and 0.025μg/kg.Average recoveries of the 19 polychlorinated biphenyl compounds were typically in the range 82%~111% with relative standard deviations being generally less than 7.3%. |
