Reactivity of peroxynitrite: Implications for Hanford waste management and remediation. 1998 annual progress report

PDF Version Also Available for Download.

Description

'The broad objective of this project is to provide quantitative mechanistic information relevant to: (i) the extent and nature of radiation-induced chemical modification of the nuclear defense waste that occurs during storage, and (ii) the extent of accumulation of peroxynitrite in the waste and its potential use in remediation. Within this context, the specific goals are: To determine the radiochemical yields of peroxynitrite in chemical mixtures simulating the various phases (salt cake, slurry, supernatant) of radioactive waste; Through mechanistic studies of metal- and CO{sub 2}-catalyzed oxidations by peroxynitrite, to estimate the extent of peroxynitrite-mediated oxidative degradation of organic waste components ... continued below

This report summarizes work after the first year of a three-year project.'
