中文名称：水质 用离子色谱法测定 溶解过氯酸盐的方法（IC）
英文名称：Water quality — Determination of dissolved perchlorate — Method using ion chromatography (IC)

标准范围
This document 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.
