  • 6 Accesses

Abstract

Phase diagrams, densities, and refractive indices of RbCl + polyethylene glycol (PEG) 1000 + H2O saturated systems at 288.15, 298.15, and 308.15 K were determined. Furthermore, a four-parameter nonlinear equation developed by Hu was used to analyze the experimental data. For the ternary system RbCl + PEG1000 + H2O, the salting-out ratio of PEG1000 on RbCl decreases with temperature, the equilibrium area containing the solid phase of RbCl and saturated liquid phase increases with the temperature. The solubility of RbCl and density decrease, while the refractive indices of the solution increase with the addition of PEG1000 in the solution.
