标准摘要
[中文适用范围]： 本国际标准描述了 15 种氯酚（2,3-、2,4-、2,5-、2,6-、3,4-和 3,5-二氯苯酚；2,3,4-、2 ,3,5-、2,3,6-、2,4,5-、2,4,6-和3,4,5-三氯苯酚、2,3,4,5-和2,3,4,土壤样品中的 6-四氯苯酚和五氯苯酚）。 该方法也可应用于其他固体样品，例如沉积物和固体废物。 本国际标准描述了酸碱液体萃取，然后乙酰化，然后液/液萃取。 然后通过气相色谱法和电子捕获检测来测定质量浓度。 该方法适用于最低质量浓度范围为约 0.01 mg/kg 至 0.05 mg/kg 的氯酚，具体取决于组分灵敏度和所用样品的数量。 在某些情况下，无法实现异构体的完全分离，在这种情况下，报告总和（例如 2,4- 和 2,5-二氯酚）。 [外文原描述]： ISO 14154:2005 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 to other solid samples such as sediments and solid wastes. ISO 14154:2005 describes an acid-base liquid extraction, followed by acetylation and then liquid/liquid extraction. Determination of mass concentrationis then carried out by gas chromatography and electron-capture detection. This method is applicable to chlorophenols at the lowest mass concentrations ranging from approximately 0,01 mg/kg to 0,05 mg/kg depending on the component sensitivity and the quantity of sample used. In some cases complete separation of isomers cannot be achieved, in which case the sum is reported (for instance 2,4- and 2,5-dichlorophenols).
