چکیده انگلیسی
Phase diagrams of detergent-based aqueous two-phase systems composed of nonylphenyl ethoxylate (4- C9H19C6H4(OCH2CH2)9OH, NP-9) non-ionic surfactant and various salt solutions were studied experimentally at 298.15 K. The salts used were magnesium sulfate, sodium sulfate and sodium chloride. The salting-out power of salts in these systems were determined and this power can be arranged with respect to the cations as Mg2+>Na+ and anions as SO42−>Cl−. The experimental results of the phase diagrams were correlated using DH-NRTL model. It was found that, this model represent the experimental liquid–liquid equilibrium data of the surfactant aqueous two-phase systems with good accuracy.
