Extraction of actinides and fission products by octyl(phenyl)-N,N-diisobutylcarbamoylmethyl-phosphine oxide from nitric acid media

Extraction and third phase formation behavior of Eu(III) IN CMPO–TBP extractants present in room temperature ionic liquid

“…The boundary of third phase formation was determined as a function of concentrations of CMPO and TBP, and temperature. Mathur et al [28] studied the variation of TBP concentration in TRUEX solution and reported the distribution ratios of several metal ions including americium (III). We also studied the variation of TBP concentration in the ionic liquid system namely 0.05 M CMPO-1.2 M TBP/bmimNTf 2 , for the extraction of americium(III) from nitric acid medium [20].…”

Extraction complexes of Pu(IV) with carbamoylmethylphosphine oxide ligands: A relativistic density functional study

“…For instance, Kolarik and Horwitz [10] studied the distribution equilibria of Np and Pu in various oxidation states with a mixture of CMPO and tributyl phosphate (TBP) in dodecane, and confirmed that Pu(IV) is highly extractable with CMPO and TBP. Mathur et al [11] reported the extraction of Pu(IV), U(VI) and Am(III) also using CMPO and TBP in dodecane. They found that the extractabilities of these actinides follow the order of Pu(IV)> U(VI)> Am(III) and suggested that the extracted complex of Pu(IV) is Pu(NO 3 ) 4 ⋅2CMPO.…”

Probing of the local environment and calculation of J.O. parameters for Eu3+ CMPO functionalized pillararene complexes by time resolved fluorescence spectroscopy

“…Several classes of ligands have been examined for this purpose, out of which malonamides [4][5][6][7][8], phosphine oxides [9][10][11], diglycolamides (DGA) [12][13][14][15][16] and carbomyl methyl phosphine oxides [17][18][19] are very popular. Within the class of carbomyl methyl phosphine oxides, octylphenyl-N,N′-diisobutylcarbomylmethyl phosphine oxide (CMPO) drew attention of the researchers due to its favorable properties [20][21][22][23]. The major drawback of CMPO is the formation of third phase.…”
