THE SEPARATION AND DETERMINATION OF RUTHENIUM IN FISSION PRODUCTS BY LIQUID- LIQUID EXTRACTION WITH PYRIDINE
A method of separating radioactive ruthenium from fission products and technetium in an aqueous solution containing sodium hydroxide and hypochlorite by liquid-liquid extraction with pyridine is discussed. In the process, ruthenium in various ionic forms and various oxidation states is oxidized to perruthenate with the hypochlorite, and the perruthenate is transferred into pyridine from the aqueous solution. The partition coefficient of perruthenate was estimated for the carrier-free and the carriercontaining cases, as well as for the case where other fission products were present. Good separation of radioactive ruthenium from other fission products was achieved with a large decontamination factor. The results were examined by a gamma -ray spectrum measured at each step of the extraction process. (P.C.H.)
