本文报道用钾、钠离子选择电极于同一试液中测定钾、钠的方法,二年的生产实践表明,该法准确度、精密度与原子吸收光度法相当,满足生产要求,操作简便,易于掌握,目前已在许多钢厂推广。
This paper reports the method for determining potassium and sodium in the same test solution by using potassium and sodium ion selective electrodes. The two years’ production practice shows that the accuracy and precision of the method are comparable with those of atomic absorption spectrophotometry to meet the production requirements. The method is simple and easy to operate Mastery, has now been promoted in many mills.
