Abstract
Abstract HIGH PURITY MOLYBDENUM, PARTICULARLY RADIOACTIVE MOLYBDENUM-99, IS SEPARATED FROM ACIDIC SOLUTION CONTAINING DISSOLVED MOLYBDENUM ALONG WITH OTHER MATERIALS BY CONTACTING THE LIQUID WITH ACTIVATED CARBON HAVING A COATING OF SILVER TO ADSORB THE MOLYBDENUM ON SAID CARBON. THE MOLYBDENUM CAN BE RECOVERED FROM SAID CARBON BY ELUTING WITH AN ALKALINE SOLUTION. THE INVENTION IS USEFUL FOR RECOVERING HIGH PURITY RADIOACTIVE MOLYBENUM-99 THAT IS USED TO PRODUCE RADIOPHARMACEUTICAL GENERATORS.
