标准摘要
[中文适用范围]: 本文件规定了水中某些挥发性有机化合物的选择性测定方法(见表1)。这些包括但不限于含卤烃和汽油组分(BTXE、TAME、MTBE和ETBE)等挥发性有机化合物。该方法适用于测定饮用水、地下水、地表水和处理后的废水中的挥发性有机化合物(见表1),其质量浓度大于0.1 µg/l。下限取决于具体化合物的量、空白值和基质。该方法对表1未列出的其他挥发性有机化合物的适用性没有被排除,但需根据具体情况检查。 表1 列出了可通过本方法测定的挥发性有机化合物 [外文原描述]: ISO 20595:2018 specifies a method for the determination of selected volatile organic compounds in water (see Table 1). This comprises among others volatile halogenated hydrocarbons as well as gasoline components (BTXE, TAME, MTBE and ETBE). The method is applicable to the determination of volatile organic compounds (see Table 1) in drinking water, groundwater, surface water and treated waste water in mass concentrations >0,1 µg/l. The lower application range depends on the individual compound, the amount of the blank value and the matrix.
