Abstract
Work has been undergoing to assess the feasibility of ion exchange resins for the removal of uranium from effluent generated during the treatment of spent uranium catalysts. A selection of resins have been screened for their potential application for this purpose: Diaion PA316, Dianion PA418, Purolite S950, Purolite S957 and Purolite S930+ and an in-house synthesized polyamine functionalized resin. Chelating resins S957 and S950+ have both shown impressive uranium extraction properties between pH 0 and pH 4 in batchwise tests. Loading isotherm studies were undertaken and data plotted to the Langmuir isotherm model. This showed that S957 observes a higher uranium loading capacity (96 mg g-1) compared to the other tested resins. Initial dynamic studies also showed resin S957 has a significant capacity for U uptake.
