碘量法测定溶解氧

Determination of Dissolved Oxygen With Iodometric Method

工业供水中的溶解氧对管道的腐蚀比较严重。本文提出用高锰酸钾——碘量法测定水中的溶解氧含量,并对该方法的测定原理及注意事项进行了深入分析,同时结合双瓶法进行误差校正,便于分析工作者在实际工作中借鉴。

Dissolved oxygen in industrial water has serious corrosion for pipelines.In this paper,potassium permanganate-iodometric method was used to determine dissolved oxygen content in water,and its measuring principle and matters needing attention were analyzed,at the same time error correction was carried out with double bottle method.
