| 摘 要： | 用等温溶解平衡法研究了Ｌｉ＋，Ｋ＋，Ｍｇ（２＋）／Ｃｌ－，—Ｈ２Ｏ五元交互体系２５℃的溶解度。该体系相图由十五个盐或复盐的结晶区构成，饱和溶液的某些物化性质的测定结果与经验公式计算结果吻合，用现代电解质溶液理论—Ｐｉｔｚｅｒ模型预测了该体系的溶解度，实验测定值与理论预测结果非常一致。

| Abstract: | The phase equilibrium diagram of the reciprocal quinary Li+,K+, Mg2+ /Cl-,-H2O at T=298. 15℃ was been calculated using Pitier et al's equations. The results of the calcula-tion have been confirmed by an experimental study of the solubility by isothermal method at 25℃, Some physico-chemical properties of solutions such as density and refractive index were determined. The caculated values of the density and refractive index of solutions by ex-perience equations was agreement with the measured values. Phase diagram of the title sysytem consists of fifteen crystallization fields. Data comparison obtained good agreement. |
