Abstract:
The use of silicalite, a zeolitic form of silica, is suggested as a means of purifying samples prior to the determination of chlorinated biphenyls (CBs), particularly those which are heavily contaminated with petroleum derived n-alkanes. Experiments using mussel, fish and sediment extracts show that CBs are recovered quantitatively after silicalite treatment of lipid extracts.
