Uranium removal from aqueous medium using Co0.5Mn0.5Fe2O4 nanoparticles

Abstract

Co 0.5 Mn 0.5 Fe 2 O 4 nanoparticles were successfully synthesized for uranium removal from aquatic media. The Co 0.5 Mn 0.5 Fe 2 O 4 was analyzed by XRD, EDX, FTIR, and DLS. The DLS analysis of Co 0.5 Mn 0.5 Fe 2 O 4 showed the size of nanoparticles in the range of 3–20\xa0nm. The removal of U(VI) ions by Co 0.5 Mn 0.5 Fe 2 O 4 was studied at different experimental conditions. The initial uranium concentrations, pH, and time parameters have a significant effect on the removal process. Isotherms data showed a favorable adsorption process of second-order kinetics. The results show that Co 0.5 Mn 0.5 Fe 2 O 4 is an effective adsorbent with a higher affinity toward the removal of uranium ions, adsorption capacities of 104\xa0mg/g.
