EXTRACTION BEHAVIOURS OF Nd(III), Eu(III), La(III), Am(III), AND U(VI) WITH SOME SUBSTITUTED MALONAMIDES FROM NITRATE MEDIUM

Comparison of sorption behavior of Th(IV) and U(VI) on modified impregnated resin containing quinizarin with that conventional prepared impregnated resin

“…Thus, the fact remains that powerful extractant agents need to separate thorium and uranium ions from co-existed metal ions present in great excess in polluted media. The procedures described in the recent literature are mostly on the basis of liquid-liquid extractions for the separation of Th(IV) and U(VI), which are either less effective or time consuming due to high matrix concentration [3][4][5][6][7][8].…”

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

“…disolvate, monosolvate, and hemisolvate) [14]. Several studies related to the extraction of acids, metal ions under varying experimental conditions have been performed to understand the extraction mechanism prevailing with the malonamide class of extractants for possible applications in radioactive waste treatments [14][15][16][17][18][19][20].…”

Recovery of Palladium from Concentrated Nitrate Solutions with N,N 2-Dimethyl-N,N 2-Dioctyltetradecy lmalonamide as New Extractant

“…N, N 2-dimethyl-N,N2-dioctylmalonamide (DM DOMA) and N,N 2-dimethyl-N,N 2-dioctyltetradecyl malonamide (DMDOTDMA) were synthesized and purified following the procedure that we described previously 21,29 .…”

“…Although malonamides have been extensively investigated for the extraction of lanthanide and actinide ions in nuclear processing industry [21][22][23] , only a limited amount of work reported involving the use of these ligands for the extraction of Pd(II) from hydrochloric acid solutions [3][4][5][6][7][8] . No systematic studies have been reported on the extraction of Pd(II) from concentrated nitrate media.…”

“…Many researchers have tried to improve and develop novel extractants, which have high extraction efficiency as well as selectivity for platinum group metals (PGMs). During the last twenty years a several of amide bidentate ligands have been often proposed for the solvent extraction process, mainly due to their faster kinetics, higher efficiency, selectivity, and complete incinerability [18][19][20][21][22] .…”
