摘要

本文讨论了笔者(Ⅰ)报提出的简化Pitzer(1980)模型中单参数的物理意义

发现该参数与水化数成正比

据此得出由离子半径预测单参数的关联式.最后预测了373.15K电解质水溶液的过量焓

从而在理论上验证了该单参数与温度的关系.

Abstract

In this paper the physical meaning of the single parameter in simplified Pitzer(1980) model is discussed. The parameter is found proportional to the hydration number of the electrolyte

therefore the correlation equation is obtained from which this parameter can be evaluated from ionic radii. The temperature dependence of the parameter is also verified by predicting the excess enthalpy of the electrolyte aqueous solutions at 373.15K.
