Liquid-liquid equilibria of aqueous two-phase poly(ethylene glycol)-potassium citrate system
Liquid-liquid equilibrium data of poly(ethylene glycol) 6000 + potassium citrate + water have been measured at (25, 30, and 35) degreesC. The binodal curves were described using a three-parameter equation, and the tie lines were satisfactorily described using the Othmer-Tobias and Bancroft equations.
