Materials and methods: The influence of pH, equilibrium time, temperature, adsorbent dosage, and initial uranium concentration on adsorption percent was investigated. Results: Obtained results declared that the pH of aqueous solutions had affected UO22+ ions removal, which was indicated by the increased removal efficiency with increasing solution pH till pH 3. Conclusion: Experimental data were verified with Langmuir and other isotherms and were found to be well fitting with Langmuir isotherm models. A feasibility study for the whole process was performed.
