Application of MXene for remediation of low-level radioactive aqueous solutions contaminated with 133Ba and 137Cs

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.
