| description | The treatment of radioactive wastewater is one of the major problems in the current research. With the development of nuclear energy, the efficient removal of <sup>99</sup>TcO<sub>4</sub><sup>−</sup> 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 <sup>99</sup>TcO<sub>4</sub><sup>−</sup>/ReO<sub>4</sub><sup>−</sup> and has good selectivity in the nitric acid system. The kinetics of the reaction of p-(Amide)-PAM with <sup>99</sup>TcO<sub>4</sub><sup>−</sup>/ReO<sub>4</sub><sup>−</sup> was studied. The results show that p-(Amide)-PAM has a fast adsorption rate for <sup>99</sup>TcO<sub>4</sub><sup>−</sup>/ReO<sub>4</sub><sup>−</sup>, 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 <sup>99</sup>TcO<sub>4</sub><sup>−</sup> from radioactive wastewater. |
