Solid and Liquid Phase Equilibria of Li+, K+, Ca2+∥Cl–H2O Quaternary Systems at 298.15 and 273.15 K

Abstract: Brine deposited in Chaerhan salt lake belongs to the chloride type and can be simplified into the hexnary system Li+, Na+, K+, Mg2+, Ca2+, Cl––H2O. The known solubility data indicate that significant salting-in effects exist in its subsystems of KCl–LiCl–H2O and KCl–CaCl2–H2O, which inevitably affect the properties and solubility behavior of actual brine. In this work, the solubility behavior study and phase diagram determination are extended to the quaternary system of Li+, K+, and Ca2+∥Cl––H2O. The phase equ… Show more

“…The wet solid-phase samples are separated rapidly by isothermal filtration and dried with a filter paper for chemical analysis and solid species identification by X-ray powder diffraction (XRD). , However, the CO 2 ’s influence on the wet solid in the experiments cannot be avoided because of both the solid–liquid phase separation process of filtration and the detection process of XRD exposed in air. The XRD pattern shows that BaCO 3 existed but other solid species existed outside the studied equilibrium system.…”
