电解质水溶液的固—液平衡计算

CALCULATION OF SOLID-LIQUID EQUILIBRIUM OF AQUEOUS ELECTROLYTE SOLUTIONS

本文以扰动理论为基础建立了电解质溶液的状态方程。并将其用于电解质水溶液的固—液平衡计算。同时与Guggenheim模型,Bromley模型,Meissner模型和Pitzer模型进行了比较。本文模型与Bromley模型,Meissner模型及Pitzer模型具有大致相同的精度。取得了令人满意的结果。

An state equation based on perturbation theory is presented for electrolyte solutions. The equation state is used to predict solid-liquid equilibrium of aqueous electrolyte solutions. Meanwhile, compared with the Guggenheim model, the Bromley model, the Neissner model and the Pitzer model, this equation state has similar accurary, satisfactory rsalts are obtained.
