Investigation on the Diluent Effect on Solvent Extraction Processes of Trivalent f-Elements by Acidic Di-Alkyl Organophosphorus Extractants
Solvent extraction is the most common chemical technique used in hydrometallurgical separations and purification of transition metals and f-elements. Solvent extraction of metallic cations, such as the f-elements, needs ...
Complexation of Tetravalent Fission Products and Plutonium(IV) with Polyaminopolycarboxylate Ligands
Management of problematic tetravalent fission products and actinides present in the back end of the nuclear fuel cycle presents important scientific and technical challenges concerning the reprocessing and disposal of used ...
High Yield Fission Product Separations and Quantification For Nuclear Forensic Applications
Strontium-90 and its daughter, yttrium-90, have cumulative fission yields of approximately 6 percent from the thermal neutron induced fission of uranium-235. With these high yields, Sr and Y are prevalent following an ...
Influence of Near-Field Materials on the Durability of Nuclear Waste Glass
A reliable and effective method of nuclear waste disposal is necessary for the continuing use of nuclear energy. Borosilicate glasses are the currently accepted method of the disposal of these wastes, though a thorough ...
TECHNETIUM (IV) COMPLEXATION CHEMISTRY WITH POLYAMINO POLYCARBOXYLATE LIGANDS
99Technetium (t½ = 2.1×105 y) constitutes approximately 6.1% of the cumulative yield of thermal 235U thermal fission. In the +7 oxidation state, technetium has high aqueous solubility and forms the anionic structure TcO4- ...
