| Abstract: | Summary We have optimized a procedure for the determination of PCBs in waste automotive engine oils based on sulphuric acid treatment followed by percolation through chromatographic silica cartridges for sample clean-up. The resulting solutions are assayed by GC-ECD or GC-MS/SIM. The recovery is 93% and the analysis time is less than 2 h. The proposed method is suitable for routine analysis. |
