水质.某炸药及其相关化合物的测定.用UV探测的高效液相色谱法(HPLC

[中文适用范围]： 本国际标准规定了饮用水、地下水和地表水中某些爆炸物的测定方法，特别是硝基甲苯、硝基胺和硝酸酯以及相关化合物（副产品和降解产物），例如表1中列出的那些。 根据样品类型和待分析化合物的类型，硝基芳香族化合物和硝胺的工作范围下限可假定为 0.1 µg/l 至 0.5 µg/l（在某些情况下，较低值）限制可延伸至 0.05 µg/l）。 硝酸酯的工作范围下限可以假设更高（0.5 µg/l 或更高）。 类似的化合物，特别是其他硝基芳族化合物，也可以通过该方法测定，但必须在每种情况下检查其适用性。 [外文原描述]： ISO 22478:2006 specifies a method for determination of certain explosives, in particular nitrotoluenes, nitroamines and nitrate esters, and related compounds (by-products and degradation products), such as those listed in Table 1, in drinking water, groundwater and surface water. Depending on the type of sample and the compound to be analysed, the lower limit of the working range for nitroaromatics and nitramines can be assumed to be between 0,1 micrograms/litre and 0,5 micrograms/litre (in some cases, the lower limit may be extended down to 0,05 micrograms/litre). The lower limit of the working range for nitrate esters may be assumed to be higher (0,5 micrograms/litre or more). Similar compounds, in particular other nitroaromatics, may also be determined by this method, but its applicability will have to be checked in each individual case.
