摘要
盐湖是天然存在于地球表面上的水与盐类共存的复杂体系。在盐湖中不断发生着盐类的沉积析出或溶解、混合等过程,即相变化过程。水盐体系相图是水盐体系相平衡的几何表示,在描述水盐体系相变化过程中,因其具有的明显的几何直观性,得到了最广泛的应用。从水盐体系相图在盐湖化学分类、卤水蒸发过程、卤水中各成分的分离提取、水盐体系热力学模型的建立和应用等多方面论述了相图的应用。从盐湖资源开发利用的实际问题出发,列举了作者计算获得(非引自通常的参考文献或出版物)的众多典型实例。
Salt lakes are naturally existing mixtures body of salts and water on the earth. Deposition or dissolution of salts, mixing of brines and water occur continuously. All of them are phase change processes. Phase equilibrium studies the law of phase changes of a system as a branch of chemistry. So phase diagram of salt-water system has been fol3nd wide applications in Salt Lake Chemistry. Many aspects of salt- water system applications phase diagram were described in the present paper. Examples of application given in this paper were elaborately designed by the author.
