摘要：

A simple, sensitive, precise and specific method for the isolation of planar PCB congeners having four, five and six chlorines in environmental samples is presented. On average, recoveries of 3,3',4,4'; 3,4,4',5; 3,3',4,4',5 and 3,3',4,4',5,5' (IUPAC No 77, 81, 126 and 169) planar PCB congeners from spiked Aroclor mixtures were 94 +/- 7.2, 82 +/- 5.4, 93 +/- 3.9 and 96 +/- 2.5%, respectively; while recoveries from spiked dolphin blubber samples were 87 +/- 4.0, 70 +/- 2.3, 91 +/- 2.8 and 97 +/- 2.3%. As compared to previously published methods, this methodology saves both time and materials, i.e. solvents, and eliminate the use of benzene, a highly carcinogenic solvent, which requires extreme care in handling by the analyst.
