摘要
本研究旨在将湿度法的应用范围扩大到含有挥发性电解质的系统，特别是湿法冶金工艺中使用的盐酸水溶液。为此，我们将 Pitzer-Simonson-Clegg 模型与湿度法相结合，以确定 NaCl-HCl-H2O 和 NaCl-KCl-HCl-H2O 系统的热力学特性。在温度为 298.15 K 和总离子强度为 0.3 至 7.5 mol/kg 的条件下测量了水活度和溶解度。利用粉末 X 射线衍射（XRD）对固态进行了表征。盐酸的平均离子活度系数和矿物盐 MCl（M+ = Na+、K+）在含有氯化钠或氯化钠和氯化钾的盐酸水溶液中的溶解度的预测值与以前发表的文献数据以及本研究获得的溶解度测量值一致。
Thermodynamic Properties of NaCl-HCl(aq) and HCl-NaCl-KCl(aq) at a Temperature of 298.15 K
The aim of this study was to expand the application of the hygrometric method to systems that contain volatile electrolytes, specifically, aqueous hydrochloric acid solutions used in hydrometallurgical processes. To achieve this, the Pitzer–Simonson–Clegg model was combined with the hygrometric method to determine the thermodynamic properties of the NaCl-HCl-H2O and NaCl-KCl-HCl-H2O systems. Water activity and solubility were measured at a temperature of 298.15 K and at total ionic strengths ranging from 0.3 to 7.5 mol/kg. The solid state was characterized by using powder X-ray diffraction (XRD). The predicted mean ionic activity coefficient of HCl and the solubilities of mineral salts MCl (M+ = Na+, K+) in aqueous hydrochloric acid solutions containing sodium chloride or sodium and potassium chloride were consistent with previously published literature data as well as the solubility measurements obtained in this study.
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.
