Can a pH meter measure fluoride ions?
Some users asked if the pH meter can measure fluoride ion? The answers given by the technicians are as follows for reference!
Can. However, the reference electrode and the fluoride ion measuring electrode need to be connected, and the linear regression equation of the negative logarithm of the fluoride ion concentration with respect to the potential must be manually performed.
Give an example to illustrate how to measure fluoride with a pH meter in the phsj-3f laboratory?
1. First configure the fluoride ion electrode and reference electrode;
2. Next, configure fluoride ion standard solution and TISAB ionic strength regulator;
3. Then measure the potential value of each standard solution, draw a graph of the fluoride ion concentration relative to the potential, and perform a linear regression;
4. Finally, measure the potential value of the sample and calculate the concentration.
