Amidoxime-Functionalized MXene beads for the effective capture of uranium from wastewater with high fluoride concentrations

•A highly efficient adsorbent was prepared and used for the treatment of uranium wastewater.•MXene/PAO hydrogel beads exhibit outstanding adsorption capacity under different conditions.•MXene/PAO hydrogel beads have excellent practicality coupling through columns.•Adsorption mechanism under F− conditions is the coordination of MXene and amidoxime to uranium complexes.
