摘要：
Effect of acidity and hydrogen peroxide and ethanol concentrations on the degree of precipitation of uranium peroxide in solutions of various compositions was studied. The efficiency of the peroxide purification of uranium to remove REEs and strontium was experimentally verified. A radionuclide Eu-152 served as a representative of REEs. The behavior of Sr was examined on its analog, Ba-133.
