Abstract:
The influence of the difference between electrode blank potential and the potential drift on the determination of fluoride by fluoride selective electrode is investigated.An one point calibration method is proposed to ensure the stability, reproducibility and accuracy in the sample analysis.
Key words:
fluoride electrode,
blank potential,
potential drift,
one point calibration
