摘要
介绍了pH值测量的原理,描述了测定KCl/NaCl样品pH值时纯水、搅拌、pH电极的维护保养对测量结果的影响。分析了出现这些结果的主要原因,并通过选取标样对测量结果修正、读取稳定数值、合理使用、正常保养电极的方法,解决了测量结果重复性差、耗时长,多个试验结果不一致的问题。
The principle of pH measurement is described , the influencing factors that the water , the agitation , pH electrode is described on the determination of pH value of potassium chloride or sodium chloride. The main resson for these results is analyzed,and the standard sample is selected to revise the measurement results, reading stable values, using reasonable,normal maintenance electrode method to solve the problems of measurement result repeatitive, time-consuming and the experimental results which are not consistent.
