TL;DR: A critical review provides a judicious assessment of the available literature on ionic-liquid-based Aqueous Biphasic Systems and addresses two of the main applications of ionic liquid-based ABS: extraction of biomolecules and other added-value compounds, and their use as alternative approaches for removing and recovering ionic liquids from aqueous media.

TL;DR: The key accomplishments and future challenges to the field are discussed, with particular emphasis on the major lacunas found within the IL community dedicated to separation processes and by suggesting some steps to overcome the current limitations.

TL;DR: The results noticeably indicate that it is suitable to use aqueous solutions of hexafluorophosphate- and tetrafluoroborate-based ILs at moderate temperatures while acidic conditions promote the anion hydrolysis, even at low temperatures.

TL;DR: The influence of water content in the surface tension was studied for several ILs as a function of the temperature as well as afunction of water mole fraction, for the most hydrophobic IL investigated, [omim][PF(6)], and one of the more hygroscopic IL, [bmim][ PF(6].

TL;DR: From experimental measurements of the temperature dependence of ionic liquid solubilities in water, the thermodynamic molar functions of solution, such as Gibbs energy, enthalpy, and entropy at infinite dilution were determined, showing that the solubility of these ILs in water is entropically driven and that the anion solvation at the IL-rich phase controls their solubabilities in water.
