Potential approach to how radioactive elements could be 'fished out' of nuclear waste

[font size=5]Potential approach to how radioactive elements could be ‘fished out’ of nuclear waste[/font]
[font size=3]Manchester scientists have revealed how arsenic molecules might be used to ‘fish out’ the most toxic elements from radioactive nuclear waste - a breakthrough that could make the decommissioning industry even safer and more effective.
Elizabeth Wildman, a PhD student in the research group led by Professor Steve Liddle based at The University of Manchester, has reported the first examples of thorium with multiple bonds to arsenic to exist under ambient conditions on multi-gram scales where before they had only been prepared on very small scales at temperatures approaching that of interstellar space (3-10 Kelvin). The finding is to be published in the leading journal Nature Communications.
“Nuclear power could potentially produce far less carbon dioxide than fossil fuels, but the long-lived waste it produces is radioactive and needs to be handled appropriately,” said Elizabeth Wildman, from Manchester’s School of Chemistry.
“In order to find ways of separating, recycling and reducing the volume of nuclear waste, research has focussed on developing our understanding of how elements like thorium and uranium interact with elements from around the periodic table to potentially help improve nuclear waste clean-up.”
