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.
