Abstract

An extended Flory-Huggins model with two electrostatic terms (the Debye-Huckel and the Pitzer-Debye-Huckel) has been presented to investigate the liquid-liquid equilibrium data for the quaternary system containing PEG, KH2PO4, surfactant and water at 303.15K and the interaction parameters between surfactant-polymer as well as other species were calculated. The obtained deviations demonstrated that these models can correlate the experimental data with good accuracy. It was found that addition of PEG as well as increasing the temperature can shift the bimodal curves of aqueous two- phase systems containing surfactant and salt.
