Abstract

MXene is an innovative multilayered material that has been prepared by an acid-salt (HCl + NH₄F) etching route and tested for the removal of ¹³³Ba and ¹³⁷Cs in radioactive conditions for the first time. MXene has exhibited high uptake capacity of about 154.9 and 121.5 mg g^-1 for ¹³³Ba and ¹³⁷Cs, respectively, in 0.01 mol L^-1 solution and using 5 g L^-1 of adsorbent at natural pH.
