本文报导了使用钠、钾离子选择性电极以直接电位法或改进的零点电位法测定玻璃成品、原料中Na_2O和K_2O含量的方法。试液中Na~+、K~+离子浓度调节在10~(-3)—10~(-4)M间。为保证试液的离子强度和pH恒定。研究中使用了含有乙醇胺和盐酸的TISAB溶液。在2分钟内电位即达稳定状态。从一系列分析数据得到的标准偏差σ为: Na_2O%=11.57%时, σ=0.1%; K_2O%=1.13%时,σ=0.05% This paper reports the method of determining the contents of Na_2O and K_2O in glass products and raw materials by direct potential method or improved zero potential method using sodium and potassium ion selective electrodes. The concentration of Na ~ + and K ~ + in the test solution was adjusted between 10 ~ (-3) -10 ~ (-4) M. To ensure that the ionic strength of the test solution and pH constant. TISAB solutions containing ethanolamine and hydrochloric acid were used in the study. In 2 minutes the potential reached a steady state. The standard deviation σ obtained from a series of analytical data is σ = 0.1% for Na 2 O% = 11.57% and σ 0.05% for K 2 O% = 1.13%
