Chelate Extraction of Metals into Ionic Liquids
نویسنده
چکیده
In the solvent extraction of metal cations into ionic liquids, use of Brønsted acid-type chelate extractants has some advantages including simplicity in controlling extraction selectivity by selecting suitable aqueous phase pH values and simple back-extraction recovery of the extracted metals using acid solutions. In this review, various fundamental and applied research on metal extraction using the “ionic liquid chelate extraction system” since 2001 are described in detail.

Extraction behavior of divalent metal cations in ionic liquid chelate extraction systems using 1-alkyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imides and thenoyltrifluoroacetone.
The extraction behavior of several divalent metal cations (M(2+)) in ionic liquid chelate extraction systems was investigated using several 1-alkyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ionic liquids ([Rmim][Tf(2)N]) as extraction solvent and thenoyltrifluoroacetone (Htta) as extractant. The behavior was compared with that using less hydrophobic 1-alkyl-3-methylimidazolium hexa...

متن کاملExtraction and Separation of Rare Earth Metal Ions with DODGAA in Ionic liquids
In order to apply ionic liquids (ILs) to the separation of rare earth metals, liquid-liquid extraction of a series of rare earth elements into the ILs was investigated mainly using 1-octyl-3-methylimidazolium bis(trifluoromethyl sulfonyl) imide, [C8mim][Tf2N], with N,N-dioctyldiglycol amic acid (DODGAA) as the extractant. A higher selectivity was exhibited for the heavier rare earth elements as...
متن کاملSeparation of cobalt and nickel by solvent extraction with two mutually immiscible ionic liquids.
The proof-of-principle for the separation of metals by solvent extraction using two mutually immiscible ionic liquids is given. Cobalt was extracted from the ionic liquid 1-ethyl-3-methylimidazolium chloride to the ionic liquid trihexyl(tetradecyl)phosphonium bis(2,4,4-trimethylpentyl)phosphinate. A distribution ratio of 44 was obtained. Cobalt could be selectively separated from nickel, with a...
