本文考虑了一个简化盐水体系液相成分分析的方法。用这个方法,在二盐和水的三组分体系中,只要和液相平衡的固相是一个定组成的化合物,例如纯盐,盐的某水合物等,都只要分析液相中一个组分就可以算出另外一个组分和水的含量。所以能够如此做,是因为我们可以把三组分体系中的二个组分先用固定比例配成液体,而得与液相平衡的固定出它的溶解度就行了。本文也讨论了这样做法的限制,准确度和它是否可以推广到多元体系。一般说来,组分愈多,也就愈可简化。应用这个方法求研究NaCl-NaAc-H_2O的体系是适宜的,特别是还没有好的分析方法来定Na~+及Ac~-。在本文中,只要分析Cl~-离子。本文求出NaCl-NaAc-H_2O在20℃时的相图。
In this paper, we consider a method to simplify the liquid composition analysis of brine system. In this way, in the three-component system of di-salt and water, as long as the solid phase in equilibrium with the liquid phase is a definite compound, for example, a pure salt, a hydrate of a salt, or the like, Points can be calculated from another component and water content. Therefore, we can do this because we can fix the two components of the three-component system first by using a fixed proportion to make the liquid balance the liquid and fix its solubility. This paper also discusses the limitations, accuracy, and whether it can be extended to a multi-dimensional system. In general, the more components, the more simplified. It is appropriate to apply this method to study the NaCl-NaAc-H 2 O system. In particular, there are no good analytical methods to determine Na ~ + and Ac ~ -. In this paper, we only analyze Cl ~ - ions. In this paper, the phase diagram of NaCl-NaAc-H_2O at 20 ℃ is obtained.
