将Harvie和Weare(1980)的矿物溶解度模型推广到Na-K-Mg-Ca-H-Cl-SO_4-OH-HCO_3-CO_3-CO_2-H_2O八组分体系。该模型基于Pitzer(1973)和他的合作者关于电解质水溶液热力学的半经验方程。该模型使用许多可用于许多子系统的可用等压、电动势和溶解度数据来进行参数化。在比参数化法更复杂的系统中，通过与实验数据的比较，证明了模型的预测能力。讨论了电解质水溶液化学模型的基本特征以及pH与溶液平衡性质之间的关系。
The mineral solubility model ofHarvieandWeare(1980) is extended to the eight component system, Na-K-Mg-Ca-H-Cl-SO4-OH-HCO3-CO3-CO2-H2O at 25°C to high concentrations. The model is based on the semi-empirical equations ofPitzer(1973) and co-workers for the thermodynamics of aqueous electrolyte solutions. The model is parameterized using many of the available isopiestic, electromotive force, and solubility data available for many of the subsystems. The predictive abilities of the model are demonstrated by comparison to experimental data in systems more complex than those used in parameterization. The essential features of a chemical model for aqueous electrolyte solutions and the relationship between pH and the equilibrium properties of a solution are discussed.
