“…Recovery of these metal ions is a challenging task because of high acidic environment associated with them [1][2][3]. Extraction and preconcentration of these valuable metal ions from other fission products is extremely important not only from the point of view of their limited resource availability, but also to reduce their quantum for disposal as radioactive wastes [4].…”

“…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.…”

Diamides and phosphine oxides having many types of central frames were synthesized and employed in order to determine the behavior of the actinides (An)(III), (IV), (V) and ( Measurement of the D value at different extractant concentrations gave information on the extraction reaction and extraction ability. From the present work, the best extractant is BDPPM, due to the strong affinity provided P=O group and its bidentate form resulting in six-membered ring chelation. However, this extractant has too low a solubility in n-dodecane. From the properties required for application, e.g., high solubility in n-dodecane, easy organic synthesis, gasification by combustion and high actinide extractability, into consideration, diglycolamide (DGA) is a promising extractant for radioactive waste treatment.

“…The extraction of An(III) and Ln(III) using diamide compounds is influenced by the structure of their coordination sites and the nature of the substituents on the amide nitrogen. Thus far, various diamide compounds consisting of some methylene groups and functional groups between amide groups and various substituents on the amide nitrogen have been researched and developed [1][2][3][4][5][6][7]. In our laboratory, N,N -dimethyl-N,N -diphenylpyridine-2,6-dicarboxyamide (DMDPhPDA), which possesses a pyridine ring between the amide groups and methyl and phenyl groups on the amide nitrogen, was synthesized; further, its extraction properties were investigated [6][7][8].…”
