Gamma Radiolysis of TODGA and CyMe₄BTPhen in the Ionic Liquid Tri-n-Octylmethylammonium Nitrate

Selective extraction of trivalent actinides using CyMe4BTPhen in the ionic liquid Aliquat-336 nitrate

“…The use of CyMe 4 BTPhen in [A336][NO 3 ] diluent can be nonetheless justified, knowing its high stability against radiation-induced degradation. 31 In addition, distribution ratios exceeding 10 for Am( iii ) and Cm( iii ) with sufficient separation from Ln( iii ) can already be achieved within contact times no longer than 30 min (however further studies will be required to verify if such solvent can be of practical use in continuous processes). With respect to the selectivity of the system, the solvent composed of 0.01 mol L −1 CyMe 4 BTPhen in [A336][NO 3 ] clearly favors the extraction of An( iii ) over Eu( iii ).…”

“…Indeed, some types of ionic liquids proved to show a much higher stability towards ionizing radiation. 31,32 The low vapour pressure of ionic liquids renders them safer to use than the more common aliphatic diluents. In addition, the high intrinsic electrical conductivity of ionic liquids can prevent the build-up of static charge in the organic solvent, a phenomenon sometimes encountered when using molecular diluents for solvent extraction processes, which can result in re.…”

Dosimetry and methodology of gamma irradiation for degradation studies on solvent extraction systems

“…This study opens perspectives for future research using flexible, high dose rate pooltype gamma irradiation facilities on novel solvent extraction systems, such as newly developed diglycolamides [19,46] or ionic-liquid-based systems. [47][48][49] 2 Experimental…”

Solvent Extraction Studies for the Separation of Trivalent Actinides from Lanthanides with a Triazole-functionalized 1,10-phenanthroline Extractant

“…27 Moreover, TODGA was found to have a higher radiation stability in [A336][NO3] than in aliphatic diluents. 28 The effect of replacing 2 (1,2,4-) triazine moieties by 2 (1,2,3-) triazole moieties in the case of the BTP complexants for An(III) and Ln(III) separation was demonstrated in the hydrophilic, tridentate complexant 2,6-bis[1-(propan-1-ol)-1,2,3-triazol-4-yl)]pyridine (PyTri-Diol). 21,22 It proved to be a viable CHON-compliant alternative for the previously suggested SO3-Ph-BTP molecule in the i-SANEX process.…”
