A radiochemical method for the determination of fission ruthenium in aqueous solutions is described, which does not require distillation to effect radiochemical purity. The use of potassium periodate and sodinm hypochlorite to retain ruthenium in an alkaline solation in the ruthenate and perruthesate state permits removal of many fission products from ruthenium by coprecipitation with zirconium hydroxide. The ease of dissolution of finely divided ruthenium metal with alkaline potassium periodate or sodium hypochlorite adds flexibility. Approximately 1 hour is required for an analysis in duplicate, with precision and accuracy comparable to the distillation method.
