Abstract (en)
1. A process for separating technetium-99m from molybdenum-99 bound to alumina, using eluents from nuclide generators, which comprises fixing on the alumina a copper salt in a weight ratio of Cu to Al2 O3 between 1 : 10 to 1 : 5000, preferably 1 : 50 to 1 : 300, by dissolving the copper salt in water and suspending the corresponding quantity of acid alumina in the resulting solution, subsequently adjusting the pH to a value between 4 and 9, preferably between 6.5 and 7.5, separating the alumina loaded with copper and drying it at temperatures between 120 and 250 degrees C.
