BS PD ISO/TS 17951-2:2016规定了水、废水中氟化物的测定方法 通过连续流动分析（CFA）检测废水。任何不溶或络合的氟化物都会转化为 通过自动连续流动蒸馏程序从硫酸/磷酸中提取氟离子。 蒸馏液中的氟离子采用流动分析法，使用镧-茜素络合剂和 光谱检测。本方法适用于工业废水、废水、地表水、， 地下水，渗滤液。当该方法应用于饮用水分析时，加热器和 蒸馏装置是不必要的。一些饮用水含有高浓度的铝和锌 铁对于饮用水，ISO 17951的本部分适用于低浓度饮用水 干扰。不适用于含有大量悬浮物的样品。在ISO 17951的本部分中，描述了两个工作范围: 工作范围I:0.1 mg/l至1.0 mg/l；工作范围II:1.0 mg/l至10 mg/l。校准溶液的规格应相应调整。交叉引用:ISO 3696ISO 6353-2ISO 8466-1ISO 8466-2ISO 5667-3ISO 5725-2购买时可用的所有现行修订版均包含在本文件的购买中。

BS PD ISO/TS 17951-2:2016 specifies a method for the determination of fluoride in waters, waste waters and effluents by continuous flow analysis (CFA). Any insoluble or complexed fluoride is converted to fluoride ion by an automated continuous flow 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. When this method is applied to the analysis of drinking water, a heater and a distillation unit is unnecessary. Some drinking water contains high concentration of aluminium and iron. In the case of drinking water, this part of ISO 17951 is appropriate to drinking water with low interferences. It is not applicable to samples which contain large amount of suspended matter.In this part of ISO 17951, two working ranges are described:working range I: 0,1 mg/l to 1,0 mg/l;working range II: 1,0 mg/l to 10 mg/l.The specification of the calibration solutions are to be adapted accordingly.Cross References:ISO 3696ISO 6353-2ISO 8466-1ISO 8466-2ISO 5667-3ISO 5725-2All current amendments available at time of purchase are included with the purchase of this document.
