Recent studies highlighted that Ionic Liquids are potential replacement for conventional organic solvents in various fields. However, their cost is the measure hindrance for their potential application. For their optimum applications, regeneration of Ionic Liquids is very important. The regeneration required separation and use of the ionic liquid efficiently after the reaction. What are the potential recovery methods for regeneration of Ionic Liquids in industrial applications?
Ionic liquids are green solvent which can potentially replace the conventional solvents if and only if its recovery and reuse compensates its cost. Having said that there are several methods such as Liquid-liquid extraction, and nanofilteration membrane separation are being tested for the separation products and recovery and reuse of IL. You can have a look at NF membrane in our recent publication

Ionic Liquids have many potential physical and chemical properties, such as non-flammability, low volatility, low melting point, recyclability, high thermal stability, high conductivity, and wide electrochemical window as compared to conventional organic solvents so many scientist considered ionic Liquids as a replacement of conventional organic solvents. for more detail read my paper

Recovery method depends upon the application in which you are using Ionic Liquids.
The main advantages of ionic liquids is their lack of vapour pressure and almost infinite choice of cation/anion combinations, allowing for good tunability of their properties. As such, the best methods for recovery are based on extraction and drying under vacuum.
