水质 选择性一元酚类的测定 第2部分:衍生化气相色谱法

[中文适用范围]： ISO 8165 的本部分规定了五氟苯甲酰氯 (PFBC) 衍生化后通过气相色谱法测定苯酚的方法。 它特别适用于饮用水、地下水和中度污染的地表水的检查。 使用这种方法，与提取程序相比，可以获得更低的检测限。 由于其他反应性化合物（例如胺和某些情况下的醇）也可能发生反应，因此该方法并不适用于所有情况下的废水检查。 应根据具体情况调查废水检查的适用性。 该方法可以测定表 1 中所列浓度范围≥0.1 μg/l 的酚类物质。 其他单价酚也可以使用此方法进行分析，但需要根据具体情况检查其适用性。 [外文原描述]： This part of ISO 8165 specifies a method for the determination of phenols by gas chromatography, following pentafluorobenzoyl chloride (PFBC) derivatization. It may in particular be applied to the examination of drinking water, ground water and moderately contaminated surface water. With this method, lower limits of detection may be obtained compared with extraction procedures. Since other reactive compounds such as amines and in some cases alcohols may also react, this method is not applicable in all cases to the examination of waste water. The applicability to the examination of waste water should be investigated for each individual case. This method allows the determination of the phenols listed in Table 1 in a concentration range > 0,1 mg/l. Other monovalent phenols may also be analysed using this method, but the applicability needs to be checked for each individual case.
