Abstract
A method for the determination of organohalogens by gas chromatography using electron capture (EDC) and mass‐spectrometric (MS) detection was developed for sediments from lakes and sludges of water treatment plants. The method was described and separate techniques for sample preparation were investigated to compare the retrieval rates and the best approach to the “real value”. With the help of solid‐liquid‐phase‐ and liquid‐liquid‐phase extraction sulphur, most of the organosulphur compounds and carbon acids were effectively removed. The compounds were identified by comparing temperature programmed retention indices with those of reference compounds and by high‐resolution GC/MS.
