摘要:

论证了测定氟化物时当氟电极洗涤的最大空白值不同和电极电位漂移的情况下,用一点校正法解决样品测量中的稳定性和重现性差及准确度不高的问题。

关键词: 氟电极, 空白电位值, 电位漂移, 一点校正法

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
