Simulation and Prediction of Solubility for the Quaternary System Containing Lithium, Sodium, Magnesium and Chloride at 273.15 K

Abstract:

Solubilities of the quaternary system containing lithium, sodium, magnesium and chloride at 273.15 K were calculated using Pitzer ion-interaction model and its extended HW model. The values of the Pitzer single-salt parameters β⁽⁰⁾, β⁽¹⁾, β⁽²⁾ and C^φ for LiCl, NaCl, and MgCl₂, the mixed ion-interaction parameters θ_Li_,Mg, θ_Li_,_Na, θ_Na_,_Mg, ψ_Li_,Mg,Cl, ψ_Li_,_Na_,_Cl and ψ_Na_,_Mg_,_Cl, and the Debye–Hückel parameter A^φ in the quaternary system at 273.15K were derived. Based on the Jänecke indexes, the phase diagram was plotted. This study affords the necessary parameters for solubility predictions of complicated systems and establishes a theoretical basis for the separation of these valuable minerals from salt lake brine.
