National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Fundamental Chemistry, Characterization, and Separation of Technetium Complexes in Hanford Waste.

DE2004828439

Publication Date	2002
Page Count	24
Abstract	The ultimate goal of this project is to separate technetium from Hanford tank waste. Our prior work with Hanford waste has shown that a large portion of the technetium in some tanks is not pertechnetate (TcOd) and is not easily oxidized to it. This has serious repercussions for technetium partitioning schemes because they are designed to separate this chemical form. Rational attempts to oxidize these species to Tc04* for processing or to separate the non-pertechnetate species themselves would be facilitated by knowing the identity of these 5 complexes and understanding their fundamental chemistry.
