摘要
等压法是电解质溶液热力学性质研究中常用的实验方法。文章主要从等压法的原理、等压设备的改进和等压法在含锂、硼的水溶液体系热力学性质研究中应用方面进行了总结,归纳整理了含锂的氯化物、硫酸盐、硼酸盐在不同温度、不同体系中的Pitzer单盐参数和混合离子作用参数;总结分析了硼酸盐溶液等压法研究新成果,指出了硼酸盐电解质溶液热力学性质等压法研究的未来发展方向。
Isopiestic method is a common experimental method used in the study of the ther- modynamic property of electrolyte solutions. The principle of isopiestic method, the development of isopiestic equipment and the application of isopiestic method in the field of thermodynamic proper- ties of aqueous solutions containing boron and lithium ions have been summarized; the Pitzer single salt parameters and mixing ion interaction parameters containing lithium, chloride, sulfate, borate i- ons at different temperatures and different systems were introduced in details. The some new results on thermodynamic properties of borate solution by isopiestic method were analyzed, and the new trends in the future on the thermodynamics of borate electrolyte solutions by isopiestic method were also pointed out.
