探讨用自动电位滴定仪标定标准滴定溶液,并与国家标准中以指示剂判定滴定终点的方法进行了比对。结果表明,自动电位滴定法标定EDTA、硝酸银标准滴定溶液,滴定结果准确度高,数据重现性高于标准法,可满足化验室分析工作的需要。
The standard titration solution was calibrated by automatic potentiometric titrator and compared with the method of judging the end point of titration with indicator in the national standard. The results showed that EDTA and silver nitrate standard titration solutions were calibrated by automatic potentiometric titration. The results of titration were highly accurate and the data reproducibility was higher than that of standard method, which could meet the needs of laboratory analysis.
