摘要
本文对固定干扰法测定离子选择电极选择性系数的原理进行了讨论,提出了实验过程中应满足的三个条件,导出了一个容易设计计算机程序的方程。通过对几个实例的实验数据进行计算机处理,并和传统的图解法结果作了比较,表明二者结果基本一致。
Three conditions must be satisfied when selectivity coefficients of an ion selective electrode are determined by fixed interference method. Besides the fixed concentration of interfering ion and the constant ionic strength, the valence of the counter-ion of interfering ion is equal to that of counter ion of response ion here. The experimental data can be treated with a computer program.
