At present, most units use millivoltmeters to measure fluoride. This method needs to find the concentration results on semi-logarithmic coordinate paper, and the calculation process is long. The pM-3 Ion Meter can be used to directly read the fluoride ion concentration.
1 reagent
Fluoride standard application solution (called B solution), 1.00m1 of this solution contains 5.00µg fluorine; total ionic strength adjustment buffer solution (called TISAB).
2 Determination of fluoride in various water samples
Preparation of standard calibration solution and water sample test solution: use three 15m1 burners and prepare according to Table 1.
