Detection of Hexachlorobenzene Residues in Dairy Products, Meat Fat, and Eggs

Abstract

A rapid, one column chromatographic method using deactivated Florisil for the cleanup of fatty foods is described. Hexachlorobenzene which is only partially recovered by multiple residue methods is recovered in excess of 80%, using the method described. A gas chromatographic column containing a mixture of DC- 200 and QF-1 as stationary phase for the separation of hexachlorobenzene from a-benzene hexachloride is also described.
