Summary Chemical extraction of 239Pu and 241Am from a Rocky Flats soil matrix was studied at 50°C using four ligands; citric acid and ascorbic acid at pH 2, EDTA and carbonate at pH 10. The soil was treated for a -12hour reaction period with ozone gas prior to the addition of ligands. With the carbonate ligand, the ozone treatment continued during the entire extraction. High Pu removal was found at pH 2 with ascorbic acid and pH 10 with carbonate. Both maintained redox conditions during the… Expand
