• Resumen

  • During the past decade, ¡onic-liquid-based aqueous biphasic systems (IL- based ABS) have been the focus of a significant amount of research, and excellent and comprehensive reviews are nowadays available. Rather than focusing on the phase equilibria and the phase separation mechanisms of ABS, this chapter provides an assessment of the current status of implementation of this liquid-liquid approach in the extraction, concentration and purification of biomolecules/solutes/products from real matrices.

    Examples on the successful use of IL-based ABS in the extraction/purification of value-added compounds from plant matrices and from extracellular media are provided. The use of IL-based ABS as an extraction and concentration methodology is also discussed, focusing on two main approaches: control of environmental samples and monitoring of human health or abuse of drugs. Finally, and due to the rapid development and design of extraction processes based on ILs, the use of IL-based ABS for the treatment of aqueous effluents contaminated with ILs is also presented.
