The aim of the study is to formulate experimental protocols to quantify the polarity (or, equivalently, hydro-philicity/phobicity) of thermoresponsive solvents as a function of temperature. The developed method will be employed to characterize a range of solvents for temperature swing solvent extraction (TSSE), to elucidate the relationship between solvent polarity and water miscibility, ion partioning, and solubility in saline aqueous medium.
