适用范围：This International Standard describes the gas chromatographic determination of 15 chlorophenols (2,3-, 2,4-2,5-, 2.6-. 3.4- and 3,5-dichlorophenol; 2,3,4-, 2,3,5-, 2,3,6-, 2,4,5-, 2,4,6- and 3,4,5-trichlorophenol, 2,3,4,5-and 2,3,4,6-tetrachlorophenol and pentachlorophenol) in soil samples. This method can also be applied toother solid samples such as sediments and solid wastes.This International Standard describes an acid-base liquid extraction, followed by acetylation and thenliquid/liquid extraction. Determination of mass concentration is then carried out by gas chromatography andelectron-capture detection.This method is applicable to chlorophenols at the lowest mass concentrations ranging from approximately0,01 mg/kg to 0,05 mg/kg depending on the component sensitivity and the quantity of sample used. In somecases complete separation of isomers cannot be achieved, in which case the sum is reported (for instance2,4- and 2,5-dichlorophenols).
