Phase equilibrium and protein partitioning in aqueous two-phase systems containing imidazolium ionic liquids and surfactant at low voltage levels

In this paper, the binodal data of aqueous two-phase system (ATPS) containing imidazolium-based ionic liquids (chlorinated 1-ethyl-3-methylimidazole, [Emim]Cl), and a non-ionic surfactant (octylphenol polyethoxylene, Triton X-100) was obtained by means of the cloud point method in the temperature intervals T = (288.15–308.15) K. It was found that the [Emim]Cl/Triton X-100 ATPS was sensitive to temperature and had a long phase segregation time....
