本文对氢氧化钾（KOH）水溶液的电导率进行了评述。开发了浓度与密度相关的经验相关性，以比较以KOH重量百分比和KOH摩尔浓度给出的比电导率数据。关于电导率的现有数据相互关联，并与实验数据进行比较。基于这些比较，使用特定组的报告数据来开发将KOH水溶液的比电导率与温度和浓度相关的方程。该经验关联式是在0-100 ℃温度下在0-12摩尔浓度范围内得出的。该相关性已与See和白色提出的相关性进行了比较，并在建模的浓度范围内显示出更高的准确性。(c)2006年国际氢能协会。由爱思唯尔有限公司出版。保留所有权利。
This article gives a critical review of the current data on the specific conductivity of aqueous potassium hydroxide (KOH) solutions. Empirical correlations relating concentration to density were developed to compare specific conductivity data given in weight percentage KOH and molarity of KOH. Available data on specific conductivity is related with respect to one another and compared to experimental data. Based on these comparisons, specific sets of reported data were used to develop an equation relating specific conductivity of aqueous KOH to temperature and concentration. This empirical correlation was developed over a molarity range of 0-12 at temperatures of 0-100 degrees C. The correlation has been compared with that proposed by See and White and shows greater accuracy over the concentration range modeled. (c) 2006 International Association for Hydrogen Energy.
