Uranium (VI) sorption using an anionic exchanger resin in the presence of sulfate anions, namely amberlite 910, was the subject of current study. Batch sorption experiments were carried out to evaluate the influence of operational parameters such as pH, contact time, initial concentration and existence of various anions (including phosphate, sulfate, chloride, fluoride, and nitrate) in the solution on amberlite 910 sorption behavior. Kinetics study revealed that the pseudo-second-order model showed better curve-fitting regression of the experimental data than the pseudo-first-order one. Freundlich isotherm was also provided well mathematical description of sorption process than the Langmuir one. It was also revealed that the existence of various anion species in the solution could strongly affect the sorption of uranium using amberlite 910 anion exchanger resin.
