Uptake of uranium (VI) ions using an anion exchanger resin, namely amberlite CG-400, was studied through this work in the presence of sulfate anions. Impact of various parameters including pH, contact time, initial concentration of uranium ions and intrusion with different anion contents (phosphate, chloride,sulfate, nitrate and fluoride) was examined on the sorption performance of the resin. An estimation of sorption process was also performed using isotherm and kinetics equations, which led to conformity of Freundlich and pseudo second-order models with experimental data, respectively. The maximum adsorption capacity (qmax) was found to be 63.29 mg g-1. Presence of various anions species in solution show that uranium sorption using amberlite CG-400 anion exchange resin could strongly be affected.
