Isolation of planar polychlorinated biphenyls by carbon column chromatography Academic Article uri icon


  • 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. © 1991.
