Abstract

Task-specific ionic liquids (TSILs) of a novel class, with the diglycolamide moietity grafted in the alkyl chain of imidazolium cation, were synthesized and characterized. Lanthanide complexation capabilities of TSILs as active components of solid phase extractants were evaluated by studies on the adsorption of lanthanides from aqueous solutions. The TSIL-based solid adsorbents prepared by immobilization of long-alkyl-chain TSILs in siliceous mesostructured cellular foams adsorb trivalent lanthanides. No extraction of lanthanides from aqueous solution into 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C₆mim][Nf₂T]) was observed at any acidity in the presence of these TSILs in the aqueous phase. This implies that TSILs suppress the extraction of lanthanides by formation of water-soluble complexes. The TSILs added to solvent extraction systems consisting of N,N,N′,N′-tetraoctyl-3-oxapentanediamide (TODGA) in [C₆mim][Nf₂T] and aqueous HNO₃ solutions show very good stripping properties for lanthanides.
