Resumo
99mTc, the product of radioactive decay of 99Mo, is one of the most used radioisotopes in nuclear
medicine. The 99Mo is produced mainly by fission of 235U targets HEU or LEU. After the
dissolution of uranium targets, chemical process for the separation and purification is performed in
chromatographic columns. This work presents a study on the behavior of 99Mo removal by
adsorption on acid and neutral alumina from nitric acid, which is the dissolution reagent for LEU
targets in the Modified Cintichem Process. Adsorption kinetics in solution of HNO3 and the
influence of pH were investigated. It was also evaluated the adsorption of 99Mo from nitric
solutions containing uranyl ions.
