TECHNOLOGY LICENSING OPPORTUNITY

Ligand-Assisted Capillary Electrophoretic Separation of Rare Earth Elements (REEs)

An efficient, eco-friendly method for separating rare earth elements (REEs).

Opportunity: Idaho National Laboratory (INL), managed and operated by Battelle Energy Alliance, LLC (BEA), offers the opportunity to explore a license and/or collaborative research agreement to commercialize this Ligand-Assisted Capillary Electrophoretic Separation system. This technology transfer opportunity is part of a dedicated effort to convert government-funded research into job opportunities, businesses, and, ultimately, an improved way of life for the American people.

Overview: Rare earth elements (REEs) are vital components for an array of technological applications, including electronics, batteries, and defense systems. Traditionally, their separation from ores has been a challenging and environmentally taxing process, primarily due to the use of volatile organic chemicals. Capillary Electrophoresis (CE) stands as a viable alternative but has been underutilized in the realm of REEs due to their similar chemical properties.

Description: This innovative technique optimizes conventional capillary electrophoresis by incorporating complexing agents in the electrolyte solution. The process begins by loading the capillary with a ligand-containing mixture and injecting the REE mixture at one end. Once an electric field is applied, the REEs migrate, and the ligand facilitates a more significant degree of separation between each REE. Early tests have shown substantially increased separation efficiency, reducing the time needed for a complete separation cycle to under 5 minutes with a theoretical plate count between 100,000 and 500,000.

Benefits:

• Accelerated separation process, reducing time from 30 minutes to under 5 minutes.

• High separation efficiency with a theoretical plate count between 100,000 and 500,000.

• Environmentally safer alternative to traditional methods involving volatile organic chemicals.

Applications:

• Rapid geological analysis of REE ores.

• High-throughput analytical chemistry of REE mixtures.

• Potential for incorporation into existing industrial separation processes.

Development Status: The technology is currently at TRL 3, with analytical and experimental proof-of-concept having been established. Future research will explore more ligands to further enhance separation efficiency.

IP Status: Provisional Patent Application No. 63/514,313, “A CAPILLARY ELECTROPHORETIC SYSTEM AND RELATED METHODS OF SEPARATING RARE EARTH ELEMENTS,” BEA Docket No. BA-1439.
