In the research activity for reprocessing, the solution containing impurities with nuclear materials are produced. It is necessary to recover uranium from the solution and to separate from impurities by safe and stable treatment methods. In this research, to develop the treatment process based on adsorption separation by using zeolites, basic study on adsorption and elution characteristics of uranyl ion to zeolites (A-type, X-type and Y-type) were performed.
