Abstract
A novel sorbent 4XADMnO (Amberlite XAD-4 modified with nano-flakes of manganese dioxide) was synthesized for improving UO

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
