چکیده انگلیسی
Experimental (liquid + liquid) equilibrium (LLE) measurements and the phase diagram have been determined for aqueous two-phase systems containing polyvinylpyrrolidone (PVP) and di-potassium oxalate or di-potassium tartrate at T = (298.15, 308.15, and 318.15) K. Also, the effects of temperature on the binodal curve and tie-lines have been studied. The Merchuk equation was used to correlate the binodal curves of these systems. Furthermore, several suitable equations were used to fit the tie-line data points. The results show that at each temperature, the agreement between the correlated and the experimental values is good with all of these equations. Also, the effects of the type of salt on LLE are discussed.
