Environmental Management Science Program. Speciation and Structural Characterization of Plutonium and Actinide-Organic Complexes in Surface and Groundwaters.

摘要

The proposed research is designed to study the association of actinides with dissolved organic complexes in subsurface waters. This study expands considerably on prior work due to the combination of Pu oxidation studies (for Pu speciation/chemical reactivity information), Pu isotope ratio work (for Pu source function information), and the detailed characterization of organic matter in size-fractionated groundwater samples. We have postulated that actinide associations with organic matter may be enhanced due to colloidal biopolymers.
