Ion-pair extraction of tetravalent plutonium from hydrochloric acid medium using crown ethers

Uranium pertraction across a PTFE flatsheet membrane containing Aliquat 336 as the carrier

“…Fission products such as Sr-91, Y-91, Zr-97, Cs-137, La-140, Ba-140, Ce-143, 144 and Gd-153, etc., were not transported at all (<0.1%) while Ru-103 and Cd-115 were transported marginally. It is important to note that Pu, which forms anionic chloro-complexes can also be removed under similar condition [20].…”

A diglycolamide-functionalized task specific ionic liquid (TSIL) for actinide extraction: Solvent extraction, thermodynamics and radiolytic stability studies

“…The valency of Pu was adjusted to the +4 state by using a few drops of 1 Â 10 À2 M NaNO 2 , which was checked by the TTA extraction method [33]. On the other hand, Pu was oxidized to the +6 state by the use of AgO followed by mild warming under an IR lamp.…”

An Approximation Method for Determining Key Extraction Constants in the Equilibrium-Analysis of Cd(II) Extraction with 18-Crown-6 Ether into Some Diluents

“…There are many studies for the metal extraction by crown compounds (L) and other extractants similar to L into various diluents, such as benzene, chloroform, 1,2-dichloroethane, and NB [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. In these studies, procedures of equilibrium analyses have become more difficult for primary users or outsiders of the field year by year.…”
