摘要：本文用离子质量恒算方程代替电中性方程,将作者开发的多相化学平衡计算方法(KZ算法)推广到易挥发弱电解质水溶液,并将复杂离解反应体系分解为两个简单体系,提出了这类系统平衡计算的一种通用方法.与Sanderson-Chien算法和Gautam-Seider算法相比,本算法具有更好的性能.计算和实验结果吻合良好.
A generalized method was presented for calculating the vapor-liquid equilibria of aqueous volatile weak electrolyte systems. By extending the KZ algorithm of simultaneous chemical and phase equilibrium calculations developed 玝y Xiao et al. (1989)to electrolyte systems with the electroneutrality equation being replaced by mass balance equations of ionic species, and splitting the complex system of dissociation reactions into two simple ones, the present approach showed better efficiency than those developed by Sanderson and Chien (1973) and by Gautam and Seider (1979). The calculated results agreed well with the experimental values.
