Application of Ionic Liquids for Solid-Phase Extraction of Trace Elements

Recovery and Separation of Metal Ions from Aqueous Solutions by Solvent‐Impregnated Resins

“…These authors also investigated the extraction of Au(III), Pt(II), and Pd(II) from HCl solutions by XAD-4 impregnated with trioctylamine (TOA) solubilized in a nonionic surfactant, i.e., polyethyleneglycol (10) ) to the phosphonium cation of the IL, i.e., R 3 R P, through chloride IX. Myasoedova et al [110] impregnated various matrices with phosphonium ILs to extract trace elements. They proved that the multi-walled carbon nanotubes and XAD-7 resins are highly promising matrices for the extraction of Pt(IV), Pd(II), and Au(III), as well as Pu(IV).…”

Quaternary Ammonium and Phosphonium Ionic Liquids in Chemical and Environmental Engineering

“…The extraction efficiency of Aliquat ® 336 was thereby remarkably higher compared with other evaluated extractants (Cyanex ® 923, tri-n-butylphosphate (TBP), bis(2, 4, 4-trimethylpentyl) dithiophosphinic acid (Cyanex ® 301), tri-n-octylamine (TOA); Pancharoen et al, 2009). Myasoedova et al (2008) evaluated different solid supports (polyacetonitrile, Amberlite XAD-7, hyper cross linked polystyrene or multi walled carbon nanotubes) with [P 6,6,6,14 ][Cl], [P 6,6,6,14 ][PF 6 ], and [P 6,6,6,14 ][BF 4 ] as solid-phase extractants for Pt(IV), U(VI) and Pu(IV) from acid solutions, achieving the best performance with polyacrylonitrile impregnated with Cyphos ® IL 101. Next to SLMs, polymer inclusion membranes (PIMs) were evaluated as solid supports for ILs.…”

Ionic liquid coated carbon nanospheres as a new adsorbent for fast solid phase extraction of trace copper and lead from sea water, wastewater, street dust and spice samples

“…Solid phase extraction (SPE) is the most widely used separation/preconcentration technique mainly due to the variety of different materials employed as sorbents [2,18]. The development of new materials as adsorbent in sample preparation has been widely exploited to obtain more selective materials with higher adsorption capacity [2,11].…”

“…The development of new materials as adsorbent in sample preparation has been widely exploited to obtain more selective materials with higher adsorption capacity [2,11]. The solid phase extractants are distinguished by fast kinetic properties, as well as by the simplicity of their preparation [18].…”
