【 摘 要 】

This project provides information relevant to: (i) the extent of radiation-induced accumulation of peroxynitrite in the Hanford waste and its roles in waste degradation and (ii) the potential applications of peroxynitrite in remediation technologies. These studies include: (1) Determinations of the peroxynitrite radiation yields in chemical mixtures simulating the various phases of Hanford waste. (2) Time-resolved mechanistic investigation of the direct radiation effects in solid nitrates and their concentrated solutions. (3) Determination of the optimal conditions for catalyzed oxidation of organic complexants by peroxynitrite. (4) Evaluation of the feasibility of using peroxynitrite for oxidative removal of chromium for more efficient vitrification.
