如何准确测定化学水中的游离二氧化碳

How to Accurately Determine the Content of Free Carbon Dioxide in Chemical Water

游离二氧化碳的含量是化学水装置的一项重要工艺参数,如何选择适当的分析方法准确测定游离二氧化碳尤为重要。测定方法有直接法和固定发两种,通过实验决定选用"固定法"测定化学水中游离二氧化碳含量,此方法灵敏度较高,滴定终点颜色易于判断,适于现场控制分析。

The content of free carbon dioxide is an important technological parameters in chemical water device,it ＇s important to select an appropriate analysis method for an accurate determination of free carbon dioxide. We have tow detection modes： the direct method and fixed method,through the experiment,we decided to choose ＂ fixed method ＂ to determine the content of free carbon dioxide,this method is high sensitivity,and also it ＇s easy to judge the color of the titration end point,it＇s suitable for control analysis on- site.
