Corrosion Behavior of Nuclear Waste Storage Canister Materials
… a technetium surrogate, rhenium was studied. Perrhenate was used as an analog for pertechnetate. As all isotopes of technetium are radioactive, rhenium was chosen as the experimental surrogate due to its chemical similarity to technetium. Electrochemical behavior was evaluated using …

The preparation of organosulfur derived electron transfer salts
… cation salts formed from these, including a perrhenate salt which is both N-protonated and oxidised, giving an overall charge of +2 on the electron donor molecule. A group of novel aldehyde-functionalised donors are discussed, one of which could lead to a Little-type superconductor, and the …

Reaction condition effects on Re(VII) sorption kinetics at the zerovalent iron-water interface
… as a potential reducing agent in the CWT. Using perrhenate (Re(VII)O4-) as a chemical analogue for 99Tc(VII)O4-, batch Re(VII) sorption experiments were conducted in ZVI as a function of pH (8.2-10.2) and nitrate concentration (0-0.1M). Zero valent iron was effective in reducing Re(VII) to …

Development of oxorhenium complexes and bimetallic Re-Pd/C catalysts for perchlorate reduction in water
… salt-resistant ReOx−Pd/C catalyst prepared from perrhenate (ReO4-) precursor is used to treat ClO4- in waste brine collected from a water treatment plant from California. Deactivation of ReOx−Pd/C in the waste brine is prevented by implementing a sequential treatment strategy where nitrate (NO3-) …

Synthesis study of size-controlled noble metal nanoparticle systems of Re, Ir, and Os using AOT-reverse microemulsion based methodologies
… slowing the tendency of Re NPs to oxidise into perrhenate. A range of advanced characterization techniques, including UV-Vis spectroscopy, ESI-MS, FE-SEM/EDX, and HR-TEM, were employed to thoroughly analyse the synthesized NPs. UV-Vis confirmed the successful reduction of the metal precursors, …

Redox-active materials for electrochemically-mediated separations
… 17-fold selective electrochemical extraction of perrhenate over nitrate. The ferrocene macromolecule motif was also extended to the generation of zwitterionic polyelectrolytes that possess pH-sensitive electrochemical behavior in both homogeneous and heterogeneous environments. Cation separation …
