摘要
本文分析了COD测量中对消解液及水样的定量要求,提出了利用定容瓶、蠕动泵及恒流—时间方法实现小剂量液体自动定量的方法,并对定量误差的来源进行了分析和探讨.
This paper analyses the requirements for the quantitative determination of oxidizing liquid and water sample in the COD measurement.By using the constant volume bottle,the squirm pump,and constant current-time, a method is proposed to realize the automatic quantitative determination of a little liquid. The source of quantitative errors is also analysed.
