摘要：

Liquid-liquid phase diagrams of surfactant-based aqueous two-phase systems (ATPS) composed of TritonX-100, as a non-ionic surfactant, and two different salts have been studied at 298.15 K. The salts used were an inorganic salt, magnesium sulfate (MgSO4), and an organic salt, sodium citrate (Na3C6H5O7). The results show that the salt MgSO4 is more capable of inducing ATPS formation than the salt Na3C6H5O7. The experimental liquid-liquid equilibrium data were correlated using a modified virial model. Good agreement was obtained with the experimental data. (C) 2010 Elsevier Ltd. All rights reserved.
