Abstract
A method and apparatus for isolating and purifying aBi radioactive isotope from anAc source using a primary column and a primary sorbent which preferentially retainsAc overBi when exposed to a compatible solvent in combination with a secondary column having a secondary sorbent which retainsBi when exposed to a mixture of the compatible solvent andBi. A 'compatible solvent' is a solvent which will preferentially removeBi radioactive isotopes from a primary sorbent without removingAc radioactive isotopes, and then allowBi radioactive isotopes removed from the primary sorbent to be retained on a secondary sorbent, without having to dilute or otherwise chemically or physically modify the compatible solvent in between exposure to the primary and secondary sorbents.
