摘要

建立了硝酸铁和氯化铁水溶液的综合热力学模型。Pitzer参数的温度依赖性是根据现有的文献数据确定的。本文对硝酸铁和氯化铁水溶液在293 K下的表面张力进行了新的测量。该模型能够准确地再现渗透系数和活度系数等热力学性质。将该模型扩展到预测这些电解质的表面张力，与表面张力的实测值吻合良好。

Thermodynamic Modeling of Osmotic Coefficients and Surface Tension of the Ferric Chloride–Water and Ferric Nitrate–Water Systems Using the Pitzer Model

A comprehensive thermodynamic model for aqueous solutions of ferric nitrate and ferric chloride was presented. The temperature dependency of the Pitzer parameters was determined based on the available literature data. New surface tension measurements were carried out in this work for the aqueous solution of ferric nitrate and ferric chloride at 293 K. The model was able to reproduce accurately the thermodynamic properties such as the osmotic coefficient and the activity coefficient. The model was extended to predict the surface tension of these electrolytes with good agreement to the measured values of surface tension.

期刊介绍： The Journal of Chemical & Engineering Data is a monthly journal devoted to the publication of data obtained from both experiment and computation, which are viewed as complementary. It is the only American Chemical Society journal primarily concerned with articles containing data on the phase behavior and the physical, thermodynamic, and transport properties of well-defined materials, including complex mixtures of known compositions. While environmental and biological samples are of interest, their compositions must be known and reproducible. As a result, adsorption on natural product materials does not generally fit within the scope of Journal of Chemical & Engineering Data.
