Abstract
Ba and Pb radionuclides can be removed from Sr in aqueous solution in both sodium acetate and acetic acid, containing 20 mg Sr carrier, by s tirring with small (0.1-0.5 g) amounts of solid manganese dioxide. In tracer experiments Sr-85 was separated with only small losses from Ba- 133 and Pb-210 by separation factors of 87 and 135, respectively. The separation factor is defined here as the % of the initial Sr-85 activi ty/ % of the initial Ba-133 or Pb-210 activity remaining in the aqueou s phase after MnO2 contact. The applicability of this technique for re moving Ba and Pb radionuclides in the analysis of Sr-90 in environment al samples (especially milk) is discussed.
