A proposed remediation technology to remove Pu and Am from Rocky Flats Plant (RFP) soil combines hot solution (80 °C) leach with complexing (e.g., citrate) and reducing (e.g., ascorbic acid or dithionite) agents. The majority of the Pu and Am in the RFP soil was associated with soil size particles of
