Zimmermann, Thomas Mayordomo, Natalia Oliveira, Augusto F. Brandt, Felix Klinkenberg, Martina Barthel, Juri Schild, Dieter Hockmann, Kerstin Stumpf, Thorsten Scheinost, Andreas C. 2026-01-30 Radioactive technetium-99 (99Tc) is present in nuclear and medical waste. Its immobilization by magnetite (FeIIFeIII2O4) has been studied in the last decades, showing that magnetite reduces pertechnetate (TcVIIO4−) to TcIV, which is either incorporated into the magnetite structure or forms TcIV-TcIV-dimers. The distribution between both phases as well as the incorporation mechanism remain, unclear. This work investigates the molecular environment of Tc after putting it in contact with presynthesized nanoparticulate magnetite as a function of pH (2 - 13) and time (up to 7 weeks). X-ray absorption spectroscopy (XAS) was combined with density functional theory methods (DFT) to decipher the mechanism of TcIV incorporation. We observed that sorption of TcIV-TcIV-dimers initially occurs at pH 5 and pH 7, while TcIV incorporation in magnetite prevails at longer times and at pH 10. We suggest that TcIV-TcIV-dimer sorption on magnetite is due to maghemitization, whereas TcIV incorporation is due to the electron transfer from sorbed Fe2+ through magnetite and subsequent release of FeII in solution (redox conveyor belt model), “burying” TcIV into the magnetite structure. DFT calculations indicate that TcIV incorporates in magnetite by an exchange of two FeII atoms for one TcIV, keeping the charge balanced by creating a vacancy. https://rodare.hzdr.de/record/4485 10.14278/rodare.4485 oai:rodare.hzdr.de:4485 doi:10.1107/S1600577520014265 url:https://www.hzdr.de/publications/Publ-42934 url:https://www.hzdr.de/publications/Publ-42933 doi:10.14278/rodare.4484 url:https://rodare.hzdr.de/communities/robl url:https://rodare.hzdr.de/communities/rodare info:eu-repo/semantics/openAccess https://creativecommons.org/licenses/by/4.0/legalcode Tc Incorporation Fe3O4 DFT XAS Data publication: XAFS and DFT insights into the kinetics and mechanisms of technetium reduction by nanoparticulate magnetite info:eu-repo/semantics/other dataset
