简介(Home)

我们的工作,通过测量、模拟和关联各种电解质溶液的化学热力学性质,从而准确预测高溶解性或难溶盐水体系的溶解度相平衡行为。为达到这些目的,我们研究溶液结构的变化规律,开发分子热力学模型,评估热力学模型的预测能力,测定混合电解质溶液的热力学性质。这些工作,有利于我们加深对电解质体系盐水相互作用的理解。其应用范围包括湿法冶金、盐化工过程以及相变储能材料的开发。

Our main work is to predict solubility of multi-component systems of highly soluble salts or slightly soluble salts by thermodynamic modeling. For this purpose, we investigate structures of electrolyte solutions by DFT calculation and UV-measurements, develop thermodynamic model based on solute speciation, evaluate prediction ability of developed thermodynamic models, measure properties (water activity and solubility) of electrolyte solutions. These research studies contribute to our fundamental understanding of component interaction in multi-component electrolyte systems, their primary application is for design of industrial processes (salt lake chemical engineering and hydrometallurgy) and heat (cold)-storage materials.
