摘要
本文提出了一种新的标定硫酸高铈标准溶液的方法——光度滴定法.详细讨论了测定条件,推导出新的计算公式.实验表明,该法精密度与准确度明显优于国家标准GB601-77(16)法.
A new method is provided for the standardization of eerie sulfate standard solution by phototitrimetric determination.The conditions of measurement were studied in details and a new calculation formula was established. The experimental result showed that the accuracy and precision of this new method were superior to the National Standard Method GB601-77(16). Relative standard deviation dropped from 1.24% to 0.47% ( n= 10 ) .
