In this work, Extraction of uranium from laboratory wastewater has been investigated experimentally.Uranium is the important element in the nuclear fuel cycle and recovery of this element from wasteproduction is very important from economical and environmental point of views. The uranium wastewas characterized and based on the ions in the waste, suitable solvent and diluent was selected. The experiments were carried out at different conditions. The extraction parameters including extractant concentration, temperature and organic to aqueous phase ratio was investigated. Optimal condition of uranium recovery from waste also was determined.
