现场测定天然水中微量氟的三点法

The Three Points Method of Determining Micro Amountof Fluorite ion in Natural Water in Situ

提出了在水源现场测定微量氟离子的离子选择性电极三点法．该法受测量条件影响较小，且操作简单、快速、灵敏度高，特别适用于野外现场分析．

In this paper the three points method for determining micro amount of fluorite ion in natural water in situ is suggested. This method is less affected by determining conditions. and simple rapid and sensitive. It is particularly suitable to determining fluorite ion in situ.
