Abstract

The binodal data and tie-line data for the PPG₇₂₅-KOH/K₂CO₃/K₃PO₄ aqueous two-phase systems were determined at 298.15 K. Three empirical equations were used to correlate the binodal data and obtained good fit effect. The tie-line composition was correlated by the Othmer-Tobias and Bancraft equations. Furthermore, the effect of salt on the binodal curve for the disquisitive systems have been discussed and it was found that anions with a higher valence are better salting-out agents than anions with a lower valence, which is corresponded to the value of salting-out coefficient and effective excluded volume values. In the investigated systems, the order of salting-out abilities of salts is K₃PO₄ > K₂CO₃ > KOH.
