Abstract

We have studied the kinetics of lipid removal using the semipermeable membrane technique (SPM) during preparation of fat rich environmental samples ibr analysis of lipophilic substances such as dioxins. This is a useful alternative to the conventional methodologies (both destructive and non-destructive). For herring fat, the dialysis was found to be almost complete after two solvent replacements. Our study also showed recoveries exceeding 80% for a series of PCDDs and PCDFs in various biotic samples. (C) 1998 Elsevier Science Ltd, All rights reserved.
