标准摘要
[中文适用范围]： 本国际标准规定了一种测定未过滤饮用水、废水、地下水和地表水中选定的壬基酚单个异构体的方法。该方法适用于单个异构体浓度在 0.001 µg/l 至 0.1 µg/l 之间，4-壬基酚（异构体混合物）总和浓度在 0.01 µg/l 至 0.2 µg/l 之间。根据基质不同，该方法也适用于浓度为 0.1 µg/l 至 50 µg/l 的废水。 [外文原描述]： ISO 24293:2009 specifies a method for the determination of selected individual isomers of nonylphenol in non-filtered samples of drinking water, waste water, ground water and surface water. The method is applicable in concentrations between 0,001 µg/l and 0,1 µg/l for individual isomers and from 0,01 µg/l to 0,2 µg/l for the sum of 4-nonylphenol (mixture of isomers). Depending on the matrix, the method is also applicable to waste water in concentrations between 0,1 µg/l and 50 µg/l.
