Radiometric determination of cesium in nitric acid fission product solutions by substoichiometric precipitation with molybdophosphoric acid
Creators
Description
A radiometric method has been developed for the determination of cesium in nitric acid solutions by substoichiometric precipitation with molybdophosphoric acid (HMP). The fundamentals of the precipitation process were studied in particular the influence of the concentration of nitric acid, molybdate ions, Cs ions, and different fission products, such as Tc, Pd, Sr, Ce, Rh, Zr, on the yield of precipitation. Results of analyses in the 0.3 to 1 mg Cs/ml are discussed. The method can be used for the determination of Cs in highly active solutions of the nuclear fuel cycle. The relative standard deviation is +- 5%. (author)
