Batch and column studies on uranium adsorption by Amberlite XAD-4 modified with nano-manganese dioxide

A novel sorbent 4XADMnO (Amberlite XAD-4 modified with nano-flakes of manganese dioxide) was synthesized for improving UO 2 2+ ions sorption in aqueous medium from low radioactive waste. The new sorbent was characterized using EDX, XRD and FTIR analyses. Uranium sorption was investigated in both bat...

Description
Summary:A novel sorbent 4XADMnO (Amberlite XAD-4 modified with nano-flakes of manganese dioxide) was synthesized for improving UO 2 2+ ions sorption in aqueous medium from low radioactive waste. The new sorbent was characterized using EDX, XRD and FTIR analyses. Uranium sorption was investigated in both batch and column studies at different operating conditions. Different kinetics, isothermal and dynamic models were applied for the results of the carried experiments. The developed sorbent was successfully utilized for UO 2 2+ ions sorption in safeguards application.
