标准摘要
[中文适用范围]： 本文件规定了水（例如饮用水、矿泉水、原水、地表水、部分处理过的水或游泳池水、饮用水/游泳池水处理厂的废水）中溶解的高氯酸盐的测定方法。 对样品进行适当的预处理（例如基质消除）可以直接测定高氯酸盐≥ 1 µg/l。 工作范围受分离柱离子交换能力的限制。 可能需要将样品稀释至工作范围。 [外文原描述]： ISO 19340:2017 specifies a method for the determination of dissolved perchlorate in water (e.g. drinking water, mineral water, raw water, surface water, partially treated water or swimming pool water, waste water from drinking/swimming pool water treatment plants). Appropriate pre-treatment of the sample (e.g. matrix elimination) allows a direct determination of perchlorate ≥ 1 µg/l. The working range is restricted by the ion-exchange capacity of the separator column. Dilution of the sample to the working range can be necessary.
