Abstract
This research was undertaken to evaluate the transport of nitrosyl ruthenium in an aquatic environment. To study the migration of RuNO com plexes in an aquatic environment, it was necessary to develop a method ology for determining the chemical forms of nitrosylruthenium which might be present under different en vironmental conditions. Special em phasis was directed to RuNO-nitro complexes in general and RuNO-di nitro complexes in particular. Ruthenium is one of the predomi nant fission products found in reactor fuel-reprocessing wastes. It has two moderately long-lived radioisotopes, 106Ru, with a half-life of 365 days, and 103 Ru, with a half-life of 42 days (1). Process solutions obtained by dissolu tion of irradiated nuclear reactor fuel in nitric acid are known to contain varying proportions of two classes of nitrosylruthenium (RuNO) complexes, namely, the nitratoand nitroforms (2) (3). Some of the RuNO com plexes present problems in fuel-re processing operations. Hence, consid erable research has been undertaken to study the chemistry of these com plexes under the acid environments which prevail in the fuel-reprocessing operations. However, little is known
