Novel ionic liquids for liquid–liquid extraction

Liquid-Liquid Extraction of Ferric Ions Into the Ionic Liquids

“…At present days, ionic liquids become increasingly interesting for researchers in a wide range of fields. They play an important role for many current technologies from hydrometallurgy to food processing [1]. These substances gained attention of scientists due to their unique and tunable properties depending on the exact structure of the anion and cation [2].…”

“…Although the possibility of tuning the properties of ionic liquids can lead to their specific use, ionic liquids can also be used as a substitute for conventional organic solvents, when they may be used in nearly any area where the conventional molecular solvents are traditionally employed. Liquid-liquid extraction is being one of the most evident application for the purpose of purifying or concentrating the substances [1]and it also seems to be very promising way for the separation of metals and radionuclides in the treatment of an industrial waste.…”

“…The imidazolium ionic liquids are usually used as solvents for suitable extracting agents and they have been successfully tested in the extraction of a variety of metals [1,4]; in many cases the combination with extracting agent caused the synergistic effect. [5].…”
