Extraction of Actinides(iii), (Iv), (V), (Vi), and Lanthanides(iii) by Structurally Tailored Diamides

Separation of Am, Cm and Lanthanides by Solvent Extraction with Hydrophilic and Lipophilic Organic Ligands

“…In this regard, the proposed diamide extractants up to now show mostly the same trends as that for DOODA [2]. It is expected that the combination of both ligands in an extraction system may increase the separation factors for individual Ln.…”

“…Recently, strong diamide-type extractants having the ether oxygen in the central frame have been developed for Am and Cm recovery from nitric acid [1][2][3][4]. These diamide-type extractants can be incinerated.…”

Actinides Extractability Trends for Multidentate Diamides and Phosphine Oxides

“…For instance, many different structures of monoamides, diamides, carbamoylmethylphosphine oxides, and diphosphine dioxides have been developed particularly in the last three decades [1][2][3][4][5][6]. However, there are few reports concerning extractants with different central frames [7][8], because of difficulties in their organic synthesis. Besides, the forms of the central frame play an important role in actinide extraction and thus a comparison of the several types of extractant is required to determine the best chemical structure.…”

“…One of the main purposes of this work is to determine their order of extractability, and the relation of actinide extractability with their central frame are discussed. These extractants, which have been used previously [7], belong to Division 2. Diluents are used (n-dodecane or nitrobenzene) as appropriate and the D values obtained are compared under the same experimental conditions in order to determine the extraction ability trend.…”

N,N,N’,N’-Tetrabutyl-1,10-phenanthroline- 2,9-dicarboxamide as Very Effective Extraction Agent for Trivalent Europium and Americium

“…10,11 Lately, interest has shifted to the properties of tetraalkyl-diglycolamides, [12][13][14][15] with emphasis on tetraoctyl-diglycolamide (TODGA), suggested as an extractant of Pu(IV), Np(IV), Am(III), and Cm(III) in solutions with hydrocarbon diluents. [12][13][14] The ability of TODGA to extract many other metals has been discussed 15,16 and the very high extractive capacity of this agent was shown to allow its application as a solid extractant. 17 Complexation of trivalent lanthanides and actinides with several novel diglycolamide-functionalized calixarenes has been studied recently.…”
