The present process for the production of Ba-140 consists of precipitation of the Barium from dissolved slug solution as sulfate using lead carrier, metathesis of the Lead-Barium sulfates to carbonates using potassium carbonate, solution of the carbonate precipitates in nitric acid, electrolysis of the lead, evaporation of the Barium Nitrate to dryness, solution of the Barium Nitrate in water and precipitation again into hydrochloric acid-ether to extract, and final concentration of the Barium chloride.
