Abstract

The chemical behavior of binuclear oxygen-bridged nitratonitrosylruthenium complex was studied in neutral aqueous solution containing sodium nitrate. This binuclear complex has been referred to for convenience as (Ru-O-Ru) nitrate, and is formed in reactor fuel-reprocessing through solvent extraction. Following facts have been found.
(1) Nitrosyl groups of the original binuclear complex change to nitro or nitrato group by air-oxidation.
(2) A charge-negative mononuclear aquo-ruthenyl complex with nitro and nitrato groups is formed, presumably due to the decomposition and air-oxidation of (Ru-O-Ru) nitrate.
