The study of the molybdenum by alumina adsorption was studied for the improvement of technetium generators CNESTEN used for the manufacture of radiopharmaceuticals products. The molybdenum concentrations used vary between 330?M and 1.7mM, distribution of Mo between the aqueous phase and the organic phase was characterized by the percentage of adsorption (P) and the distribution coefficient (D).The optimal conditions for adsorption are in the pH range between 3-5. Followed by the adsorption of this radiosotope depending on contact time between the adsorbent and the adsorbat showed some significant effect, however the concentration of molybdenum used may change the adsorption mechanism.
