Title: Improving the recovery of Ba from Sr Resin columns using chelating agents

Journal Article · · Journal of Radioanalytical and Nuclear Chemistry

Age dating of Cs-137 sources necessitates the accurate and precise quantification of the isotope Ba-137. In previous efforts to determine the age of Cs-137 source material, variation in Ba recovery was the largest source of uncertainty. This work investigates the use of several common chelating agents (EDTA, CDTA, DTPA, and NTA) to strip barium from Sr Resin columns quantitatively in an effort to improve the reproducibility of the separation. Batch studies showed conditions in which CDTA, EDTA, and NTA may suppress the retention of Ba on the column. Follow-up column studies showed excellent removal of barium from the column with quantitative recovery in the appropriate elution fraction. Our report builds upon previous studies and establishes additional chelating agents that could be used in an age dating separation procedure
