Organic complexants are present in some radioactive wastes and can challenge waste disposal as they may enhance subsurface mobility of radionuclides contaminant species via chelation. The principal sources organic complexing agents low level (LLW) originate from chemical decontamination activities. Polycarboxylic decontaminants such citric oxalic acid interest currently there is a paucity data on their biodegradation at high pH under conditions. This work explores the biogeochemical fate...
Biodegradation of citrate occurred under LLW repository relevant conditions with Ni and U present. Citrate biodegradation led to the formation insoluble sulfides or nanocrystalline U( iv )–phosphate may promote Ni/U retention in repositories.
Glutathione (GSH) sensitive vesicles were prepared by the self-assembly of amphiphilic inclusion complexes. These novel chemically supramolecular amphiphiles are anticipated to have applications in drug delivery; nanocarriers can protect encapsulated cargo and release it via triggered degradation high concentrations GSH. Additionally, sensitivity GSH indicates that dynamic covalent disulfide bond at vesicle surface be used for post-modification nanocarrier a thiol-disulfide exchange,...
The legacy spent nuclear fuel ponds (SNFPs) at Sellafield house a diverse inventory of waste from the early Magnox reactors.These reactors used uranium metal as encased in magnesium non-oxide cladding.Corrosion cladding results release radionuclides, primarily uranium, and formation brucite (Mg(OH) 2 ) phases which are present both corroded sludge base pond suspended water column colloids 1 .Colloids have potential to mobilise insoluble providing an important pathway for radionuclide...
Microorganisms can play an important role on the behaviour of colloids in natural and engineered environments, which turn control mobility associated metals radionuclides. This is especially true nuclear fuel cycle, where radionuclides (including uranium) interact with a broad range inorganic colloids. relevant to legacy spent ponds at Sellafield, house diverse inventory waste from early Magnox reactors. These reactors used uranium metal as encased magnesium non-oxide cladding. Corrosion...
