摘要
本文通过对标准方法的再研究,结合监测仪器的特有性能,提出用两点定位法测定水质样品中的氟,通过对实验样品的精密度、准确度分析,本方法的标准偏差在0.3～1.8%之间,加标回收率在93～101%之间,符合环境监测的要求。
Objective：To establish and prove the method to determine the fluorine in water sample by using the two-point locating. Method： Through the proper study to the standard method and the performancc of monitoring equipment, the article establishes the method to determine the Fluorine in water sample by using the two-point locating. Result： Through the analysis to the accuracy and precision, The RSD of the method was 0.3-1.8%, and the recoveries were 93-101%. Conclusion： The accuracy and better repeatability of determination the Fluorine in water sample can be established though the two-point locating.
