本标准规定了用2-(对磺苯偶氮)-1,8-二羟基-3,6-萘二磺酸锆分光光度法测定氟化物含量的方法。
本标准适用于饮用水中0.28 mg/L~1.6 mg/L氟化物(以F- 计)的测定。
含氟化物(以F-计)1.0 mg/L的水样中,引起0.1mg/L误差的干扰离子浓度值如下: Al3+(0.1 mg/L),Cl-(7000 mg/L),NaPO3(1.0 mg/L),SO42- (200 mg/L),PO43-(16 mg/L),Fe(10 mg/L),碱度(以CaCO3计,5000 mg/L)。碱度的干扰可用盐酸或硝酸去除,余氯干扰可用硫代乙酰胺去除,色度、浑浊较高或干扰离子较多的水样应经蒸馏法预处理。
