Pertechnetate-Induced Addition of Sulfide in Small Olefinic Acids: Formation of [TcO(dimercaptosuccinate)2]5– and [TcO(mercaptosuccinate)2]3– Analogues

Abstract: Technetium-99 (Tc) is important to the nuclear fuel cycle as a long-lived radionuclide produced in ∼6% fission yield from U orPu. In its most common chemical form, namely, pertechnetate (TcO), it is environmentally mobile. In situ hydrogen sulfide reduction of pertechnetate has been proposed as a potential method to immobilize environmental TcO that has entered the environment. Reactions of TcO with sulfide in solution result in the precipitation of TcS except when olefinic acids, specifically fumaric or malei… Show more

“…Moreover, it is also important to consider the management of the radioactive waste after separation. In the most recent work, the separative system developed is also intended to be transformed into a containment matrix [88,197,198]. In addition, it should be noted that the constraints linked to the handling of a radioelement such as Tc often lead to the use of stable chemical analogues such as ReO4and ClO4or the 99m Tc isotope in the ultra-trace state, which is easy to detect thanks to its gamma emission.…”
