摘要
EGTA标准溶液配置后,在放置过程中,常出现棉花状的白色或绿色悬浮物。本文通过实践研究,分析了悬浮物对溶液浓度的影响程度,发现在20天内悬浮物对溶液浓度无影响。
In the process of preparing EGTA standard solution,white suspensions like cotton often appear. This paper analyzes the effect of the suspensions on the concentration of solution through experiments,and finally finds that the suspensions have no effect on the concentration of solution.
