Facilitated transport of uranium(VI) across supported liquid membranes containing T2EHDGA as the carrier extractant

Mathematical modeling of the extraction of uranium(VI) into a polymer inclusion membrane composed of PVC and di-(2-ethylhexyl) phosphoric acid

“…Studies on membrane separation of uranium have included systems based on bulk liquid membranes, emulsion liquid membranes and supported liquid membranes [18][19][20][21][22][23]. Whilst the current techniques of separating uranium are considered costeffective and relatively efficient, many workers have sought to find safer methods for separation where chemical inventories are reduced.…”

New extractant N,N′-dimethyl-N,N′-dicyclohexyl-2,(2′-dodecyloxyethyl)-malonamide (DMDCDDEMA) for radiotoxic acidic waste remediation: Synthesis, extraction and supported liquid membrane transport studies

“…Membrane stability, reusability and optimized selectivity can be achieved [29,30]. The obtained results from the SLM studies can be scaled up to industrial level to resolve the radioactive waste remediation problem [28][29][30][31][32][33]. DMDCDDEMA has been evaluated as the carrier extractant for the transport of Am(III) from acidic feeds.…”

“…These extractants were also evaluated as carrier ligands and stationary phase in supported liquid membrane (SLM) and extraction chromatography system, respectively. Such techniques were encouraged in recent studies, http to avoid the use of large extractant inventory required in actinide partitioning work [11,12,[27][28][29][30][31].…”

Theoretical Investigation on the Interactions of Isoamethyrins and AnO2+/2+ (An=U, Pu)

“…Researches show that Octyl(phenyl)‐N,N‐diisobutyl carbamoyl methyl phosphine oxide (CMPO) and UO 2 2+ can form stable complexes, and PuO 2 2+ can coordinate with 2–4 CMPO molecules . Diamide is also can be used in extraction because N,N,N′N′‐Tetraoctyl‐3‐oxapentanediamide (TODGA) can coordinate with UO 2 2+ . Shen and co‐workers found that N,N,N’,N’‐tetrabutyl‐3‐oxy‐glutaramide (TTDGA) and N,N’‐dimethyl‐N,N’‐diethyl‐3‐oxapentamide (DMDEDGA) had high efficiency on U element extraction.…”
