Facile and Selective Palladium Recovery from Acid Leachate of Nuclear Waste Glass with Hydrazine Reduction Assisted by Coexisting Chalcogens

Hydrazine reduction achieves efficient and selective recovery of Pd from an HNO3 + HCl solution dissolving various elements from high-level radioactive wastes and borosilicate-based glass components which have been eluted from a simulated nuclear waste glass. Se and Te coexisting in this system play important roles to promote the deposition of Pd.
