A. Thompson et al., A RAPID METHOD FOR THE CLEANUP OF CHLORINATED BIPHENYLS (CBS) ISOLATED FROM ENVIRONMENTAL-SAMPLES, Talanta, 45(5), 1998, pp. 1001-1006
The use of silicalite, a zeolitic form of silica, is suggested as a me
ans of purifying samples prior to the determination of chlorinated bip
henyls (CBs), particularly those which are heavily contaminated with p
etroleum derived n-alkanes. Experiments using mussel, fish and sedimen
t extracts show that CBs are recovered quantitatively after silicalite
treatment of lipid extracts. (C) 1998 Elsevier Science B.V.
