Thermodynamic modelling of phase equilibrium for water + poly(Ethylene glycol) + salt aqueous two-phase systems
The NRTL (nonrandom, two-liquid) model, expressed in mass fraction instead of mole fraction, was used to correlate liquid-liquid equilibria for aqueous two-phase polymer-salt solutions. New interaction energy parameters for this model were determined using reported data on the water + poly(ethylene...
