Ionic Liquid Aqueous Two-Phase Systems From a Pharmaceutical Perspective

Complete removal of textile dyes from aqueous media using ionic-liquid-based aqueous two-phase systems

Critical assessment of the formation of ionic-liquid-based aqueous two-phase systems in acidic media.

In this work, the ability of Na(2)SO(4) and ionic liquids to induce the formation of acidic aqueous two-phase systems (ATPS) is investigated. Ternary phase diagrams, tie lines, and tie-line lengths for several systems were determined and reported at 298 K and atmospheric pressure. It is here shown that among the ionic liquids studied only those containing long alkyl side chains at the ions and/...

Thermoreversible (Ionic-Liquid-Based) Aqueous Biphasic Systems.

The ability to induce reversible phase transitions between homogeneous solutions and biphasic liquid-liquid systems, at pre-defined and suitable operating temperatures, is of crucial relevance in the design of separation processes. Ionic-liquid-based aqueous biphasic systems (IL-based ABS) have demonstrated superior performance as alternative extraction platforms, and their thermoreversible beh...

Extraction and separation of proteins by ionic liquid aqueous two-phase system.

A satisfactory protocol of protein extraction and separation has been established based on the ionic liquid aqueous two-phase system (IL-ATPS) for the purification of bioactive substances. Compared with the effects of eight different ionic liquids, 1-octyl-3-methylimidazolium bromide ([omim][Br]) was selected as the suitable ionic liquid. Based on the single-factor experiment, an initial serial...
