Production of Ac227 and Th228 isotopes by irradiation of radium in the SM-2 reactor

Separation of terbium as a first step towards high purity terbium-161 for medical applications

“…These examples consist of extraction of lanthanides and transplutonium elements from alkaline and carbonate media can be achieved mainly via liquid-liquid extraction, [31][32][33][34][35][36] using various extractants such as quaternary ammonium salts, [37][38][39] primary amines 40 or alkylpyrocatechols. 41 There are also just a few examples of using extraction chromatography in carbonate media. 42,43 Thanks to its simplicity, ease of operation, speed, efficiency and the ease to be automated, solid phase extraction is used for the separation process.…”

Extraction of americium and europium with functionalized calixarenes from alkaline solutions

“…It also allows the use of optimum methods and formulations for solidification of radionuclides differing in the chemical behavior, which can considerably enhance the strength of the radionuclide fixation. Finally, it allows the vol-DOI: 10.1134/S1066362216010070 ume of HLW being solidified to be reduced owing to separation of large amount of salts of nonradioactive elements (sodium, iron, chromium, nickel, etc. ).…”

“…The K 2 CO 3 (KOH)-DOP system proved to be efficient for separating Am from other actinides, and also from Ce, Cs, and Fe [9]. DOP-NaOH-complexone systems show promise for intragroup separation of trivalent cations [8,10]. The maximal Eu-Am separation factor, equal to 70, was obtained in the DOP-NaOH-diethylenetriaminepenta(methylenephosphonic) acid system [10].…”
