The method for determining the content of extractable organic compounds in sediment samples

摘要

A method for determining the content of extractable organic compounds in sediment samples, comprising the steps that a sample of sediment were placed in a flask produce extraction methylene chloride, and the content of extractable organic compounds is determined after filtering the resulting extract, characterized in that methylene chloride is introduced into the flask with the portion of bottom Fat from a 5 ml methylene chloride per 1 g of the sample, extraction is carried out with placing the flask in an ultrasonic bath for 15 minutes, the extract is filtered in Khim sky glass using a filter, transmissive dispersion medium and retarding the dispersed solid phase, and then extraction is carried out stripping of methylene chloride by pouring the filtered extract by parts in a preweighed weighing bottle until they reach a constant weight, wherein the content of extractable organic compounds in the sample is determined by the difference weights pure and the filled weighing bottle.
