ISO 22743:2006规定了用于测定各种类型水(如地下水、饮用水和废水)中硫酸盐的连续流动分析(CFA)方法。该方法适用于硫酸盐(SO4)质量浓度为30 mg/l~300 mg/l的样品。其他浓度范围也是适用的,只要它们正好覆盖十年的浓度单位(例如100 mg/l至1 000 mg/l)。
ISO 22743:2006 specifies a continuous flow analysis (CFA) method for the determination of sulfate in various types of water (such as ground water, drinking water and waste water). The method is applicable to samples with a sulfate (SO4) mass concentration from 30 mg/l to 300 mg/l. Other concentration ranges are applicable, provided they cover exactly one decade of concentration units (e.g. 100 mg/l to 1 000 mg/l).
