Abstract:Hindered by the separation among radioactive elements, aluminum (Al), and rare earth elements (REEs), acid methods encounter persistent obstacles in reduction emission of ion-adsorption rare earth elements low-level radioactive residues (IREEs-LRR). This work reported a stepwise strategy for the reduction of emission and recovery of Al and uranium (U) from IREEs-LRR by alkaline and alkalescent media. As one of the main phases, Al(III)-containing compounds of IREEs-LRR were first converted into soluble NaAl(OH)… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
