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…

Removal of Plutonium-239 and Americium-241 from Rocky Flats Soil by Leaching
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
Chemical Extraction of Plutonium and Americium from Contaminated Rocky Fiats Soil
Chemical batch extraction and column leaching processes were conducted to evaluate the removal of plutonium and americium from contaminated Rocky Fiats soil. Citrate solutions in conjunction with
Plutonium association with selected solid phases in soils of Rocky Flats, Colorado, using sequential extraction technique
Plutonium contamination in the soil environs of Rocky Flats, CO, has been a potential health risk to the public since the late 1960s. Although the measurement of total activity of Pu-239 + 240 in the
Sequential extraction procedure for the speciation of particulate trace metals
An analytical procedure involving sequential chemicai extractions has been developed for the partitioning of particulate trace metals (Cd, Co, Cu, Ni, Pb, Zn, Fe, and Mn) into five fractions:
Reduction of Np(VI) and Pu(VI) by Organic Chelating Agents
The reduction of NpO{sub 2}{sup 2+} and PuO{sub 2}{sup 2+} by oxalate, citrate, and ethylenediaminetetraacetic acid (EDTA) was investigated in low ionic strength media and brines. This was done to
Actinide Environmental Chemistry
In order to predict release and transport rates, as well as design cleanup and containment methods, it is essential to understand the chemical reactions and forms of the actinides under aqueous
Remediation of Soils and Wastes Contaminated with Uranium and Toxic Metals
The presence of radionuclides and toxic metals in soils and wastes due to nuclear related activities is a major environmental concern. To restore the contaminated sites, both the radionuclides and
