摘要
从应用的角度出发,对电解质溶液模型、相平衡计算的现状与发展进行了简要的回顾,并系统地介绍和讨论了作者在这方面的工作。指出对P itzer模型和作者提出的电解质溶液水化平衡模型建立各自相应的普遍化温度关系,结合所提出的固液平衡级计算方法,可以预测工业过程所涉及的高温、高压、高浓度范围内复杂体系的热力学性质,解决此类过程集成模拟优化的瓶颈问题。此外,还介绍了离子选择性电极测定弱电解质体系热力学的方法。
The latest development in the thermodynamics of electrolyte solutions are reviewed briefly, including thetheories, experiments and their applications for the calculation of phase equilibira. The authors＇ work in these areasis introduced. The universal temperature relationship of either the hydration model or the Pitzer model, combiningwith a solid-liquid equilibria stage calculation, can be used to predict the thermodynamics properties of concentrated electrolyte solution under high temperature and pressure involved in the industrial processes. Furthermore, theion-selective electrode method for determining the avtivity coefficient of electrolyte solution was also described.
