The kinetic, equilibrium and thermodynamic characteristics of U(VI) recovery by the strong base anion exchange resin Ambersep 920U SO4 from Gabal Gattar sulfate leach liquor have been determined. Batch sorption experiments are performed to evaluate the optimum conditions at pH2, 200 mg resin dose for 120 min contact time at room temperature. The maximum sorption capacity reaches to 58 mg/g at 298 K. The kinetics data are well described by the pseudo-second-order kinetic model at different uranium concentrations. The experimental results obtained at various temperatures showed that the adsorption pattern on the studied resin has followed Langmuir isotherm model. The evaluation of thermodynamic parameters (free energy change, enthalpy change, entropy change, activation energy and sticking probability) indicate that the adsorption process is spontaneous in nature, endothermic, random and chemisorptive.
