“…Extraction behavior of Pu(IV) using TBP in C 4 mimTf 2 N as extractant has been reported by us [25] where we found the existence of dual mechanism depending on the acidity of the aqueous phase. Pu(IV) extraction behavior of octyl(phenyl)-N,N-diisobutylcarbamoylmet hylphosphine oxide (CMPO) or crown ether in ionic liquid has also been reported by Lohithakshan et al [26,27]. Ouadi et al [28,29], reported task specific ionic liquids containing 2-hydroxybenzylamine and TBP moiety for the extraction of Am(III) and U(VI),respectively.…”

“…For different extraction systems like Sr-Crown-ether, U-TBP, CMPO-Pu(IV), lanthanides-diglycolamide [16,24,26,31] the authors described the cation exchange of metal-solvate cation complex with C 4 mim + ion of ionic liquid. From the trend observed for D Pu(IV) values with increasing HNO 3 /HCl concentration for BenzoDODA in C 4 mimTf 2 N as diluent at lower acidity (<3 M) the following mechanism can be proposed:…”

The extraction of Pu(IV) from nitric acid medium using TBP has been compared with two diluents using nDodecane and a RTIL, 1-butyl-3-methylimidazolium bis(trifluoromethanesulphonyl)imide (C 4 mimTf 2 N). Kinetics of extraction was slower in RTIL compared to n-dodecane. Mechanism of extraction was found to be cation exchange at lower acidity which changes to formation of neutral complex at higher acidity greater than 1M HNO 3 for RTIL. Back extraction of Pu from loaded organic phase was equally effected using 0.1M oxalic acid and a mixture of guanidine carbonate and EDTA as strippant from both the extraction systems under study. Radiation stability and reusability studies showed promise for future application.

“…There have been many applications of ILs, including solvents for organic synthesis and liquidliquid extraction [1][2][3][4][5], gas chromatography stationary phases [6 -12] matrix assisted laser desorption/ionization (MALDI) matrices [13][14][15][16][17][18][19] and recently as ion pairing reagents for the trace analysis of anions by electrospray ionization mass spectrometry in the positive mode [20 -22].…”

Second generation ionic liquid matrices are developed, examined, and tested. They have shown a wide mass detection range (Ͻ1000 Da to Ͼ270,000 Da) for proteins and peptides with greater S/N ratios than solid matrices. These ionic liquid matrices also exhibit the ability to effectively ionize proteins of large mass without disrupting noncovalent interactions between monomers. Both the anionic and cationic moieties have been varied systematically to find an ionic liquid matrix with the best physical properties, analyte signal intensity, and widest mass detection range. It was determined that both the proton affinity and pK a of the cation have a large effect on the ionic liquid matrices' ability to effectively ionize the analyte. The ionic liquid matrices can be used to detect polysaccharides with fewer degradation products than solid matrices. N,N-diisopropylethylammonium ␣-cyano-4-hydroxycinnamate and N-isopropyl-Nmethyl-t-butylammonium ␣-cyano-4-hydroxycinnamate were the best matrices for proteins and peptides, while N,N-diisopropylethylammonium ␣-cyano-4-hydroxycinnamate and N,Ndiisopropylethylammonium ferulate were the best matrices for carbohydrates.
