Uranium removal from water by ion exchange process

Uranium is considered as one of the natural radioelements for water pollution, therefore its removal from water resources for supplying healthy water for food and pharmaceutical industries is of great importance. This research is carried out to remove uranium from water by ion exchange process. It has been on the basis of the uranium solution preparation (synthetic), the anionic resin (Dowex and Amberlite) selection, determination of void fraction (%), optimum pH, capacity of resins, optimum contact time and absorption curve. Besides Laser Fluorimetry (LF) and Flow Injectio Analysis (FIA) were used for measurement of uranium concentration. Maximum uranium absorption by the resins Dowex & Amberlite were respectively in 3 and 2.5 pH, absorption capacity of Dowex & Amberlite resins were respectively 22.50 and 16.90 (mgU/ml.R), contact time between resins and solution for Dowex & Amberlite were about 25 and 15 minutes, meanwhile, absorption velocity of uranium for Amberlite is more than Dowex. Both Dowex and Amberlite resins have appropriate ability for uranium removal from water
