Comparative Chemical Studies Between Fixed Bed and Batch Dynamic Ion Exchange Techniques for Extraction of Uranium

Leach solution of uranium from different resources was collected and characterized. Batch method and fixed column recovery of uranium from this leach liquor were carried out. Different parameters affecting the extraction of uranium from its solution using anion exchange resin were studied by using both Batch method and fixed column techniques. Applying the batch method, about 90% of uranium was extracted from its solution within 15 minutes. On the other hand, utilizing the fixed column technique, extraction of 93% of the uranium was possible using Amberlite IRA400, but this process takes a long time. Under the present conditions, it found that recovery of uranium from small volumes of these leach solution, it preferred to carry out using batch method
