Example text

The separation community has recognized combining ILs as a strategy for tuning their physicochemical properties [70], but there does not yet appear to be any consideration for how dissolution of charged metal complexes may change the interactions with the constituents of IL. Oppositely charged metal complexes may have an electrostatic interaction which prevents their effective separation. To illustrate this phenomenon, we present the crystal structure of [Tb(NO3)2(OH2)5][Th(NO3)5(OH2)2] · H2O. This compound was prepared by evaporating a solution of Tb(NO3)3 · 5H2O and Th(NO3)4 · 4H2O in methanol.

In light of these potential challenges, many countries will have to rely on recycling REEs from pre-consumer scrap, industrial residues, and REE-containing end-of-life products [1, 5]. Over the course of the last two decades, ionic liquids (ILs) have been increasingly used to separate REEs in the recycling process [6–12]. ILs are a class of molten salts that are liquid at temperatures below 100  C [13]. ILs are amenable to the recycling of REEs because the cation and anion components are readily tailored to a given process, and they offer numerous advantages over typical organic solvents, such as low volatility, low flammability, a broad temperature range of stability, the ability to dissolve both inorganic and organic compounds, high conductivity, and wide electrochemical windows [14].
