Oxidation of TcO2 and UO2 by Aqueous Mn(III)-Citrate and Mn(III)-Tartrate Under Anoxic Conditions: Implications for Technetium and Uranium Fate and Transport
Key Points
This research aims to understand how aqueous manganese solutions affect the oxidation of technetium and uranium under anoxic conditions.
Analyzed oxidation reactions of TcO2 and UO2 in the presence of Mn(III)-citrate and Mn(III)-tartrate.
Utilized laboratory experiments to simulate anoxic environments relevant to legacy nuclear waste sites.
Measured the resultant changes in the fate and transport of technetium and uranium.
Detected significant oxidation of technetium and uranium in the studied conditions.
Found that Mn(III)-citrate and Mn(III)-tartrate effectively promote oxidation processes.
Indicated potential environmental risks associated with legacy nuclear waste due to altered transport mechanisms.
Abstract
There are several United States Department of Energy (DOE) sites that have been dealing with the problem of legacy nuclear waste in the environment for many generations. Two major risk-driving...
