RESEARCH INTERESTS

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.
