Acid Dissolution of Depleted Uranium from Catalyst using Microwave

The separation process of uranium is one of the most important fields in nuclear industry because uranium is used primary in nuclear power plants. Uranium ores are treated by either acid or alkaline reagents. Uranium can be dissolved by acid or alkaline solutions. There are two oxidation states in which the hexavalent form, the oxide of which is UO3, and the tetravalent form, the oxide of which is UO2. However, depleted uranium(DU) has also been used as a catalyst in specialized chemical reaction such as ammoxidation. The preferred catalyst for propylene oxidation with ammonia was a uranium oxide-antimony oxide composition. The active phase of catalyst was known as USbO5 and USb3O10. There is pentavalent form. Waste catalyst containing DU was generated and stored in chemical industry. In this work, we removed DU from catalyst by acid dissolution
