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 TcO 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 TcO/ReO and has good selectivity in the nitric acid system. The kinetics of the reaction of p-(Amide)-PAM with TcO/ReO was studied. The results show that p-(Amide)-PAM has a fast adsorption rate for TcO/ReO, 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 TcO from radioactive wastewater.
放射性废水的处理是当前研究中的主要问题之一。随着核能的发展，高效去除放射性废水中的TcO已引起世界各国的关注。在本研究中，采用两步法合成了一种新型功能性聚酰胺聚合物p-(酰胺)-PAM。实验结果表明，p-(酰胺)-PAM对TcO/ReO具有良好的吸附性能，在硝酸体系中具有良好的选择性。研究了p-(酰胺)-PAM与TcO/ReO反应的动力学。结果表明，p-(酰胺)-PAM对TcO/ReO具有快速的吸附速率，饱和吸附容量达到346.02 mg/g，且该材料具有良好的可重复使用性。这种新型聚酰胺功能化聚丙烯酰胺聚合物材料在去除放射性废水中的TcO方面具有良好的应用前景。
