Presence of a Molecular Ligand alters the Solvent Behavior of an Ionic Liquid: A Combined Physicochemical Properties, FTIR Spectroscopy and Dynamic Light Scattering Investigation

“…[8][9][10] In the separation process of the target metal ions through solvent extraction route, ILs have been regarded as the suitable alternatives to conventional solvents due to their numerous attractive properties. [11][12][13][14][15] In this regard, the type of cation and anion plays a crucial role in determining a suitable IL for a specific extraction process. Consequently, the physicochemical properties such as dynamic viscosity, density, interfacial tension, phase separation time, glass transition temperature and other derived parameters vary as per the nature of the cation-anion combination.…”

Ligand Effect on Physicochemical Properties of Ionic Liquid

“…[6] In contrast to this, the use of polar solvents such as ionic liquids (ILs) as a suitable alternative to the molecular solvent systems drag the attention of several research groups due to their numerous intriguing properties by virtue of which they overcome all the aforementioned concerns appeared in n-DD phase. [14][15][16][17][18][19][20][21][22][23][24][25][26] Ionic liquids are solvent those consist entirely of ions and exist in liquid form under ambient conditions. [27][28][29] Replacement of volatile organic solvents by ILs in solvent extraction could lead to inherently safer processes.…”

“…Several studies have been reported in literature on the use of ILs as diluents and extractants in solvent extraction applications. [14][15][16][17][18][19][20][21][22][23][24][25][26] Employment of ILs in solvent extraction applications usually led to high extraction factors as compared to conventional molecular diluents, despite their high viscosity. In fact, there are some metal ions which are extracted by undiluted ILs without the use of any added ligands and the obvious credit must go to the sensational solvent behavior of ILs.…”

Extraction and Selective Separation of ZrIV from LnIII/AnIII Using an Undiluted Phosphonium Ionic Liquid

“…[6][7][8][9][10] Among various solvent systems comprising extractants and diluents designed for the spent fuel reprocessing application, ionic liquids (ILs) have shown persistent potentiality due to their several alluring properties. [11][12][13][14][15][16] Due to the presence of ionic moieties, ILs can very well be tuned (cation-anion combination) for a specific application. Depending on the nature of the metal ion to be extracted and the feed acidity, a particular IL can be designed with high sustainability (recyclable and reusable) value.…”
