Heavy metal ions extraction using new supported liquid membranes containing ionic liquid as carrier

Selective Cobalt over Nickel separation using neat and confined ionic liquids

“…[THN][Dca] and [TON][SCN] ILs were synthesized according to our previous paper [30] and their synthesis is reported in SI.…”

“…In recent years, sol-gel silica materials doped with functional ILs were used for recovery of alkaline and transition metals, the recovery and separation of lanthanides and yttrium and the removal of Pb(II) and Cr(VI) from aqueous effluents [19][20][21][22][23][24][25][26][27][28]. It has been observed that the immobilization of an IL on/inside a solid support increases the adsorption efficiency towards metal ions compared to silica sorbents without ILs and affords many advantages relative to classical liquid-liquid extraction [29][30][31][32]. Compared to other immobilization methods such as solid-support grafting, the confinement of ILs in an ionogel has many advantages.…”

Determination of Heavy Metal Ions and Organic Pollutants in Water Samples Using Ionic Liquids and Ionic Liquid-Modified Sorbents

“…Liquid extraction and its derivative methods are the typical assistant techniques used in pretreatment process. Since the first use of an IL as an alternative to traditional volatile organic solvents for two phase liquid-liquid extraction, many ionic liquids have shown several advantages (solvent power, viscosity, possibility to adjust the solubility by the choice of the anion and cation to improve and the transport properties, provide ion exchange interactions, electrostatic interactions and π - π interactions, and so on) over common solvents used in separation and extraction processes [52]. Several studies have used IL as an alternative solvent to concentrate metal ions [53].…”

The (CF3C(O)NH)(C6H5CH2NH)2P(O) phosphoric triamide as a novel carrier with excellent efficiency for Cu(ii) in a liquid membrane transport system

“…Although the effect of various carriers on the transport of alkali and alkaline earth metal cations through liquid membranes has been reported so far, relatively few carriers offer a selective and efficient transport of transition or heavy metal ions, 34,35 however they are also important from biological, medicinal, environmental and industrial points of view. 36,37 Competitive transport of seven metal cations among four membrane phases of chloroform (CHCl 3 ), dichloromethane (DCM), 1,2-dichloroethane (1,2-DCE) and nitrobenzene (NB) was evaluated in the presence of the PTC carrier.…”
