Abstract

Solubility data were experimentally acquired at ambient temperature using tri-sodium citrate, sodium nitrate and sodium acetate + Triton X-100 as the nonionic surfactant. The tie-lines were also obtained for solvation data. The salting-out ability of salts was studied by effective excluded volume (EEV) theory and salting-out coefficient, the results showed that tri-sodium citrate had the best result. Also, the effects of salt type on liquid–liquid equilibria were discussed. Additionally, the Othmer–Tobias and Bancroft equations were utilized to match tie-line data and to judge the reliability of the computational approach and related tie-line data.
