Modeling and Speciation Study of Uranium(VI) and Technetium(VII) with TBP

, 2020
Among the fission products present in the spent nuclear fuel, technetium exhibits a singular behavior in reprocessing operations performed by solvent extraction. Indeed, this strong acid readily dissociates to form the oxo-anion TcO4 − that may interfere

New leads for fragment-based design of rhenium/technetium radiopharmaceutical agents

IUCrJ, 2017
Multiple possibilities for the coordination of fac-[Re(CO)3(H2O)3]+ to a protein have been determined and include binding to Asp, Glu, Arg and His amino-acid residues as well as to the C-terminal carboxylate in the vicinity of Leu and Pro.

Effect of an extract of Centella asiatica on the biodistribution of sodium pertechnetate (Na^99mTcO₄) and on the fixation of radioactivity on blood constituents [PDF]

, 2008
This study evaluates the effects of an acute treatment with a Centella asiatica (CA) extract on the biodistribution of the radiopharmaceutical Na99mTcO4 and on the fixation of technetium-99m on blood constituents. Wistar rats were treated with CA extract

An Investigation of Iodovanadinite Wasteforms for the Immobilisation of Radio-Iodine and Technetium

Ceramics, 2023
99Tc and 129I are two long-lived, highly soluble and mobile fission products that pose a long-term hazard. A proposed wasteform for the disposal of radio-iodine is iodovanadinite (Pb5(VO4)3I), an apatite-structured vanadate.
