摘要
水盐体系介稳相图描述水盐体系在等温蒸发过程中所呈现的水盐溶解度关系。对于水盐体系介稳溶解度的本质,至今尚无统一成熟的见解。该文在前文研究的基础上,进一步探讨了介稳溶解度与过饱和二者之间的关系。采取Pitzer电解质溶液理论计算出了Na+,Mg2+/Cl-,SO42-H2O25℃时的介稳相图。获得了白钢镁矾在不同饱和度下的“能峰”。最后归纳出介稳相图的结构特点。
The metastable phase diagram of the salt-water system presents solubility relation in the system during isothermal evaporation. There is no any theory about the nature of the metastable phase diagram so far. We study the relation between the metastable phase diagram and supersaturation in the present paper. Prediction of the metastable solubilitie.in Na+,Mg2+/Cl-,SO42+-H2O at 25℃ was made. Structure charecteristics of the metastable phase diagram were discussed.
