文摘

Thermodynamic properties of (([EMIm]Br + LiBr + H2O) system were studied. The activity coefficients of (([EMIm]Br were determined with self-made electrodes. The Pitzer model was applied to describe the behavior of the electrolyte studied. The values of thermodynamic properties were calculated using Pitzer model. The temperature dependence of Gibbs free energy was used to calculate the enthalpy.
