Purification of Lutetium 177 |
摘要 |
Undesirable metal cation contaminants, including hafnium, can be reduced from a solution containing Lutetium-177 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 hafnium entering the solution from a glassware wall and of Lutetium 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 polytetrafluoroethylene coating facing the solution to prevent the possibility of contaminants which could interfere with later uses of the Lutetium-177 from leaching into the solution from the rubber stopper. Recipients of the Lutetium-177-containing vial can be provided with a prepackaged column of the anion exchange resin to enable such recipients to remove the hafnium which accumulated in the solution as a product of radioactive decay during shipment.
