标准溶液在贮存期间的稳定性如何,在目前所看到的文献资料中未见系统考察。由于对其贮存稳定性掌握不够,致使某些基层有关单位间隔时间很不一致。为此我们对常用六种标准溶液进行了较系统的考察。 据文献介绍高氯酸标准溶液EDTA硫酸铈标准溶液也都十分稳定。本文介绍了六种常用标准溶液贮存期间时间和温度的影响情况。
The stability of the standard solution during storage has not been systematically examined in the literature currently seen. Due to insufficient control over their storage stability, some units at the grass-roots level have very different intervals. To this end we have a more systematic examination of the commonly used six standard solutions. According to the literature introduction of perchloric acid standard solution EDTA cerium sulfate standard solution are also very stable. This article describes the effects of time and temperature on the storage of six common standard solutions.
