Synthesis of Lanthanum Catecholates for Separation of Lanthanides

open access: yes, 2020
Separating lanthanides from spent fuel rods from nuclear power plants could prolong the lifetime of a fuel rod and minimize waste. This work examined synthesis of lanthanum catecholates for lanthanide separations in an oxygenated environment (tabletop ...
