ISO/TS 17951-1:2016规定了通过流动注射分析（FIA）测定水、废水和废水中氟化物的方法。任何不溶或络合的氟化物都会通过手动蒸馏程序从硫酸/磷酸转化为氟离子。蒸馏液中的氟离子通过镧-茜素络合剂流动分析和光谱检测进行测量。本方法适用于工业废水、废水、地表水、地下水、渗滤液。不建议将其用于不需要蒸馏步骤的饮用水。 ISO/TS 17951-1:2016中描述了两个工作范围: -工作范围I:0.1 mg/l至1 mg/l； -工作范围二:1毫克/升至10毫克/升。 校准溶液的规格应相应调整。

ISO/TS 17951-1:2016 specifies a method for the determination of fluoride in waters, waste waters and effluents by flow injection analysis (FIA). Any insoluble or complexed fluoride is converted to fluoride ion by a manual distillation procedure from sulfuric/phosphoric acid. Fluoride ion in the distillate is measured using flow analysis with lanthanum alizarin complexone and spectrometric detection. This method is applicable to industrial waste waters, effluents, surface waters, ground waters, leachates. It is not recommended for drinking waters where a distillation step is not required. In ISO/TS 17951-1:2016, two working ranges are described: - working range I: 0,1 mg/l to 1 mg/l; - working range II: 1 mg/l to 10 mg/l. The specification of the calibration solutions are to be adapted accordingly.
