Abstract
The present invention relates to a process for removing radioactive ruthenium from an aqueous solution, comprising oxidizing the ruthenium in the aqueous solution of ruthenium tetroxide, extracting the resulting ruthenium tetroxide with a halogen-free aliphatic or alicyclic hydrocarbon solvent, allowing the ruthenium tetroxide to be reduced in the solvent, and separating the precipitated solid ruthenium dioxide.
