摘要
目前用于测硝酸根的方法较多,但对于工业生产而言,快速、简便、而又比较准确的方法很少。为了满足海水提取硝酸钾新工艺的要求,文章选择了离子选择电极法来测定硝酸根离子,并对存在的相关问题进行讨论。
There are many analysis methods to determine nitric radical.But a rapid,simple and relatively exact method to determine nitric radical suitable for industrial production is urgently required.In this paper,the ion-selective electrode analysis method is introduced to determine nitric radical in the new process of extracting potassium nitrate from seawater,and the relative questions of the method are discussed.
