With the development of nuclear energy, the efficient removal of ⁹⁹TcO₄^- in radioactive wastewater has attracted the attention of countries all over the world. In this study, a novel functional polyamide polymer p-(Amide)-PAM was synthesized by the two-step method. The experimental results show that p-(Amide)-PAM has good adsorptive properties for ⁹⁹TcO₄^-/ReO₄^- and has good selectivity in the nitric acid system. The kinetics of the reaction of p-(Amide)-PAM with ⁹⁹TcO₄^-/ReO₄^- was studied. The results show that p-(Amide)-PAM has a fast adsorption rate for ⁹⁹TcO₄^-/ReO₄^-, the saturated adsorption capacity reaches 346.02 mg/g, and the material has good reusability. This new polyamide-functionalized polyacrylamide polymer material has good application prospects in the removal of ⁹⁹TcO₄^- from radioactive wastewater.ToxicsHighly Selective Adsorption of ⁹⁹TcO₄^-/ReO₄^- by a Novel Polyamide-Functionalized Polyacrylamide Polymer Material.PMC96084802021ZZ109STRFML-2021-07E055A002ZDRW-CN-2021-32019YFC0605000Hu YXie MXue LLiao CQin BYang FfalseHighly Selective Adsorption of ⁹⁹TcO₄^-/ReO₄^- by a Novel Polyamide-Functionalized Polyacrylamide Polymer Material.The treatment of radioactive wastewater is one of the major problems in the current research.
