Abstract Titanium cerium ferrite (TCF) was prepared by a simple solvothermal method. The obtained TCF was applied as magnetic adsorbent for the extraction of uranium ions from aqueous solutions. The synthesized magnetic nanoadsorbent was characterized using FT-IR, XRD, Raman, BET surface area, VSM and TEM. Various parameters such as solution pH, initial concentration, sorbent dosage and rate of adsorption were investigated using batch adsorption experiments. The optimum pH was found to be 6.0 and the equilibrium was achieved in approximately 120 min. Kinetic studies indicated that pseudo-second-order kinetic model best describes the adsorption behavior. The adsorption isotherms were well fitted by Langmuir adsorption isotherm and the maximum adsorption capacity was evaluated to be 555.555 mg/g at 55 ⁰C. The thermodynamic parameters calculated from the adsorption data suggested that the adsorption of U (VI) onto TCF was a spontaneous and endothermic nature of process. The highest values of uranium desorption was achieved using 0.1 M HNO3 as the desorbing agent. The results indicate that TCF has potential as an adsorbent for sorption U (VI), using a simple, fast separation method for removal of uranium ions from aqueous solution.
Uranium is one of the most dangerous heavy metals in the environment because of its chemical toxicity and radioactivity. Excessive
