摘要
本文介绍了四氯化碳显色目视比色法测定溶解氧方法的研究过程,通过对分析方法中,标准试剂的选择,萃取剂的选择,碘化钾(KI)用量的选择,及稳定性实验,消除干扰实验,环境温度实验,方法准确度及精密度实验,表明此方法快速、准确、分析结果直观、适合应急监测。
This paper introduces the study of determination of dissolved oxygen by visual colorimetry with carbon tetrachloride. This method is proved quick and exact, clear in showing the experimental results and suit- able for emergency measurement by comparison of the choices of standard reagents, extraction solvents, the quantity of potassium iodide (KI) and tset of stability, denoisingt, environmental temperature and accuracy and precision.
