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.
