<p>Radionuclides such as actinides and lanthanides are extracted from solutions using functionalized carbon nanotubes. Phosphorous containing (such as phosphine oxides, phosphoric acids or phosphates) organic extractants and other extractants (such as crown ethers, calncrown derivatives, malonamide and diglycolamide derivatives, polyethylene glycol derivatives, cobalt dicarbollite derivatives, and N-donating heterocyclic ligands) can be employed on the surfaces and/or ends (tips) of carbon nanotubes to remove radionuclides such as various actinides and lanthanides from solutions. Extractant functionalized carbon nanotubes can be used for extracting radioactive nuclides from nuclear waste or spent nuclear fuel, which are produced and/or reprocessed from the nuclear power generation or other nuclear application. Solid-liquid separation process based on the contact of liquid radioactive waste using the extracting agents as the solid phase is an alternative.</p> |
