Describes the gas chromatographic determination of 19 chlorophenols (2-, 3-, and 4-chlorophenol, 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-, 2,3,4,6-, and 2,3,5,6-tetrachlorophenol and pentachlorophenol) in drinking water, groundwater, rainwater, waste water, sea water and surface water. This standard describes an acetylation followed by a liquid/liquid extraction and determination by gas chromatography and electron capture detection. This method may be used for all above mentioned types of water. With these methods chlorophenols can be determined over a range of concentrationsfrom approx. 0,01 µg/l to 1 µg/l, depending on the component sensitivity and the quantity of sample used. In some cases complete separation of isomers cannot be achieved. Then the sum is reported. This method may be applicable to other halogenated phenolic compounds.
