水中侵蚀性二氧化碳大于游离二氧化碳的原因分析

The Analysis of the Causes of Carbon Dioxide in Water is Greater Than that of Free Carbon Dioxide

工程水质分析中有时会出现侵蚀性二氧化碳浓度大于游离二氧化碳浓度的现象,这是不合理的。本文通过实验结果对比分析,上述现象主要是由于水中游离二氧化碳的损失及侵蚀性二氧化碳测试结果偏大造成的。通过对游离二氧化碳在水中的存在特征及取样、送样、检测等过程的分析,提出了解决这一现象的办法。

In engineering water quality analysis, it is not reasonable to show that the concentration of corrosive carbon dioxide is greater than that of free carbon dioxide. In this paper, the results are compared and analyzed by experimental results. The above phenomena are mainly caused by the loss of free carbon dioxide in the water and the partial results of the corrosive carbon dioxide test. Through the analysis of the characteristics of free carbon dioxide in water and the process of sampling, sampling and testing, this paper proposes a solution to this phenomenon.
