Influence of Mass Transfer on Bioavailability and Kinetic Rate of Uranium(VI) Biotransformation

PDF Version Also Available for Download.

Description

This research is investigating the influence of mass transfer process on the rate and extent of microbial reduction of U(VI) associated with intragrain domains in the Hanford subsurface sediments. The project will develop instrumental techniques to characterize microscopic mass transfer process at the sediment grain scale and to develop kinetic data and process models that describe microbial reduction of intragrain U(VI). Scientific knowledge and process models developed from this research will enhance our understanding on the future behavior of in-ground U(VI) at Hanford and other DOE sites where sediments contain U(VI) in intragrain domains or fracture-matrix systems.
