Liquid–liquid extraction using polymers followed by induced phase separation is a potential energy reducing technology for water–salt separation. Ternary equilibrium data have been determined and reported for the (block co)poly ethers–sodium chloride–water systems at two different temperatures at 298.15 K and 313.15 K and atmospheric pressure. The experimental data were correlated with the NRTL model, and the obtained binary interaction parameters to describe the ternary liquid–liquid systems at different temperatures are presented. The model predictions are in good agreement with the experimental data
