国标(1347—77)钠钙硅玻璃分析中,钾钠含量是用火焰光度计来测定的,准确快速。但由于国产火焰光度计还不很理想,特别是边远地区又受燃料气体的限制,所以还不能普及。性能良好的钾、钠离子选择电极为钾钠的测定提供一新途径。国内已利用钾钠电极以标准比较法测定玻璃中的K_2O和Na_2O含量。本文报告以缬氨酶素钾电极和玻璃膜钠电极在pNa计上测定玻璃中的钾钠。二年来结果良好,它具有耗资少、快速、准确等特点,亦可与火焰光度计相媲美。
National standard (1347-77) soda-lime glass analysis, potassium sodium content is determined by a flame photometer, accurate and rapid. However, due to the domestic flame photometer is not very satisfactory, especially in remote areas and by the fuel gas restrictions, it is not yet universal. Good performance of potassium, sodium ion selective electrode for potassium sodium determination provides a new way. Domestic potassium potassium electrode has been used to determine the standard comparison of glass K_2O and Na_2O content. This article reports the determination of potassium and sodium in glass by the valine potassium electrode and the sodium membrane electrode at pNa. Good results over the past two years, it has low cost, fast, accurate and so on, but also comparable with the flame photometer.
