摘　　要：前两文我们获得并讨论了用于六元体系溶解度计算合理的单独电解质Pitzer参数,及Na+,K+∥Cl-,NO3--H2O四元体系混合参数和它们的应用。此次报道对K+,Mg2+∥NO3-,SO42--H2O四元体系混合参数的研究及其在体系溶液热力学性质和溶解度预测中的应用。Pitzer patmneters of the single electrolyte in the systemNa^＋,K^＋/Cl^-,SO4^2- H2O at 298.15K have been obtained and discussed which can be used to describe thermodynamic properties and to predicate solubilities of the system in the previous papers. Pitzer mixing parameters for the quaternary system K^＋,Mg^2＋//NO3^-,SO4^2-H2O at 298.15K and their applications arc given in this paper as one of a series of the research work.
