摘要
在考证了用Ｐｉｔｚｅｒ电解质溶液理论计算Ｎａ＋，Ｃａ∥Ｃｌ－－Ｈ２Ｏ体系溶解度及密度的前提下，提出了借助于该理论、用计算机计算氨碱法制碱废清液蒸发过程中液相组成和密度的方法，运用这些计算数据可以研究废清液的析盐规律。在证实这种方法可靠性的情况下，对未知析盐规律的废清液进行了预测；计算了Ｎａ＋，Ｃａ∥Ｃｌ－－Ｈ２Ｏ体系２０℃相图数据及等密度线。
After the solubility and density of Na +,Ca ∥Cl --H 2O system are calculated with Pitzer theory of electrolyte solution,a method is presented to calculate the composition and density of the liquid in the evaporation process of waste clear liquid with the aid of Pitzer theory and computer.With these data,the crystallization law of salts i waste clear liquid can be studied.
