【 摘 要 】

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.
