摘要
工业循环冷却水中钙、镁离子的含量是一项重要指标。原有EDTA滴定法中工业循环冷却水浑浊问题导致指示剂终点不明显,故本文提出了一种基于钙离子选择电极的电位滴定法直接检测工业循环冷却水中的钙离子,并对具体试验过程进行了阐述,讨论了电位滴定参数设置问题,就电位滴定法测工业循环冷却水中钙离子含量的优点进行了阐述。
The content of calcium and magnesium ions in industrial circulating cooling water is an important indicator.In the original EDTA titration method,the turbidity of the industrial circulating cooling water led to the unclear end point of indicator.Therefore,this paper proposes a potentiometric titration method based on calcium ion selective electrode to directly detect calcium ions in the industrial circulating cooling water.In this paper,the specific test process is described,and the setting of potentiometric titration parameters is discussed.The advantages of the potentiometric titration method for measuring calcium ion content in industrial circulating cooling water are described.
