Separation of fission products based on ionic liquids: Task-specific ionic liquids containing an aza-crown ether fragment

Ionic Liquids in Separation of Metal Ions from Aqueous Solutions

“…However, its application for the recovery of Ce 4+ from bastnasite leaching liquor, containing Th 4+ and rare earth metals (RE), is limited by the presence of F -that negatively affects extraction efficiency. Because of this, neutral extractant (DEHEHP) has been added to [C 8 mim] [PF 6 ] to overcome this problem and the extraction efficiency of metal ions is compared to that in the traditional DEHEHP-heptane system (Table 3) (Zuo et al, 2009 (Luo et al, 2006a). Another type of TSIL, based on thioether, thiourea and urea derivatives, are involved as carriers in Hg 2+ and Cd 2+ liquid-liquid extraction (Visser et al, 2001c(Visser et al, , 2002b (Luo et al, 2006b).…”

The synergism observed in the presence of ILs is attributed to ion-recognition capabilities of complexing ligands, unique ionic solvation environment and ion-exchange capabilities of ILs (Luo et al, 2006a).…”

Facile Synthesis of Benzaldehyde-Functionalized Ionic Liquids and Their Flexible Functional Group Transformations

“…These so-called task-specific ionic liquids [10] or a much larger family of task-specific onium salts [11] can be utilized as soluble supports for organic synthesis, supported reagents or catalysts [12], and scavengers in solution phase combinatorial synthesis [13,14] with high affinity for the ionic liquid phase. Task-specific ionic liquids are compatible with a variety of organic transformations and have proven to be useful for the extraction of specific chemicals [15]. The applications of functionalized ILs for the synthesis of inorganic materials have also been reported by several groups in recent years [16,17].…”

Extraction Behavior of Divalent Metal Cations in Ionic Liquid Chelate Extraction Systems Using 1-Alkyl-3-methylimidazolium Bis(trifluoromethanesulfonyl)imides and Thenoyltrifluoroacetone

“…Many researchers have reported on the IL solvent extraction of metal cations, [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] and several reviews concerning the method have been published. [35][36][37][38] In the use of an IL as an extraction solvent, however, the recovery of the extracted metals is a serious problem because the IL phase cannot be evaporated.…”
