摘要: Abstract Thermodynamic study of the aqueous mixed electrolyte system containing 1-ethyl-3-methyl imidazolium bromide ([EMIm]) and lithium (LiBr) was performed on galvanic cell type:[EMIm] -ISE | [EMIm] Br (m1), LiBr (m2), H2O Br-ISE over total ionic strengths from 0.01 to 2.25 mol kg−1. Various series salt molal ratios (r = m[EMIm]Br/mLiBr = 0.1, 0.2, 1.0, 5.0) [EMIm]Br single solution were used at T= (298.2, 303.2, 308.2 313.2) K P = 0.1 MPa. The Pitzer ion-interaction model employed determine activity coefficients for studied system. mixing interaction parameters evaluated obtained calculate mean solute species, osmotic excess Gibbs free energies whole systems. Furthermore, temperature dependence energy also applied enthalpy
