Increase yields of gadolinium (Gd) and other rare earth elements from coal fly ash using ionic liquid extraction
Develop new Kläui ligand chelates for rare earth element extractions
As part of our contribution to the NuChemE mission, which supports waste remediation efforts at Savannah River National Laboratory (SRNL), the Fortier group at UTEP is exploring more efficient ways to extract gadolinium, a neutron poison, from waste materials such as coal fly ash. To support this effort, we are investigating the coordination and complexation chemistry of novel chelators, with a focus on the Kläui metalloligand. This chelator has a high affinity for binding various metal ions. Key attributes of the Kläui ligand include acid-base resistance, air-water stability, and an adaptable chelating site capable of accommodating metal ions of varying sizes. Its high degree of modulation makes it a versatile, "one-size-fits-all" chelator, adjustable to a wide range of conditions.
In addition, this project involves the synthesis and characterization of molecular inorganic compounds, offering students hands-on experience with f-elements. This work provides valuable insights into the complexities of nuclear waste remediation and delivers critical workforce development, equipping students with the expertise and knowledge essential for helping address the nuclear challenges of legacy waste at SRNL and other sites.
Develop cyclone separation systems for extraction of Gd from coal fly ash using supercritical carbon dioxide
Model gadolinium (Gd) supply chain
The New Mexico State University's Center for Supply Chain Entrepreneurship is currently engaged in a comprehensive analysis of the supply chain for NuChemE project materials, emphasizing rare earth elements. The team assesses competing applications, maps pricing trends, compiles import and export data, evaluates current and projected global market sizes for various rare earth elements, and identifies critical suppliers and their capabilities.
A primary objective of this project is workforce development for the U.S. Department of Energy's Office of Environmental Management (DOE-EM). As part of this effort, the team encourages supply chain and engineering students to enroll in courses developed through the project to foster a multidisciplinary approach to learning. This initiative seeks to broaden students' understanding and enhance their skills, preparing them for future roles in DOE-EM engineering projects.
