Abstract
Various methods have been studied for the extraction of polychlorophenols from bottom sediments for the subsequent gas-chromatographic determination as monochloroacetic acid esters, i.e., extraction with toluene and dichloromethane after the dehydration of the matrix, extraction with isopropanol without dehydration on mechanical shaking, sonication, and in a Soxhlet apparatus. It has been found that the recovery depends on the method of treatment of bottom sediment samples, the RSD value did not exceed 10–20%. The recovery in the extraction with toluene on mechanical shaking or sonication was 70–80%. The limits of detection for polychlorophenols were 1–3 ng/g calculated for a dry weight.
