ABSTRACT:
Undesirable metal cation contaminants, including cadmium, can be removed from a solution containing Indium-111, on a bed of an anion exchange resin. The thus purified solution can be stored and transported in a polypropylene vial, to prevent the possibility of cadmium entering the solution from a glassware wall and of Indium from being lost from the solution by chemically reacting with a glassware wall. The vial can be sealed with a rubber stopper which has a polytetrafluroethylene coating facing the solution to prevent the possibility of contaminants which could interfere with later uses of the Indium-111 from leaching into the solution from the rubber stopper. Recipients of the Indium-111-containing vial can be provided with a prepackaged column of the anion exchange resin to enable such recipients to remove the cadmium which accumulated in the solution as a product of radioactive decay during shipment.
