摘要
本文报告了对pH计的连续多次校准法和玻璃电极的氢氟酸再生法的实验研究结果。提出pH计的校准至少要连续进行两次,用5%氢氟酸按一定程序处理玻璃电极,可恢复其性能。
This paper reports on the experimental results of several occasion calibration method of pH meter and the hydrofluoric acid regeneration method of glass electrode,and points that the calibration of PH meter should be made at least two times,and the glass electrode should be treated with 5% hydrofluoric acid by certain procedures,so that its performance will be restored.
