Abstract

Driven by the growth in nuclear energy consumption, the capture of hazardous contaminants like radioactive iodine poses a critical challenge. Porous organic polymers (POPs) offer a promising solution as efficient adsorbents. In this work, we report the synthesis of two nitrogen-rich POPs, BA-Mel and BA-TAPT, via an imine condensation reaction. The presence of abundant nitrogen atoms and phenyl rings provides abundant active sites for the efficient adsorption of radioactive iodine in both the liquid and gas phases. In the gas phase, BA-Mel showed an iodine uptake of 4.0 g g⁻¹, while BA-TAPT achieved 4.7 g g⁻¹. While in hexane and simulated seawater, BA-Mel exhibits superior adsorption capacity due to its highly porous structure, high nitrogen content, large surface area, and excellent dispersion in solution. Overall, this study highlights that incorporating nitrogen-rich sites into POP is a viable approach for developing highly effective adsorbents for the capture of iodine.

高效吸附放射性碘的富氮巴比妥酸衍生多孔有机聚合物

在核能消费增长的推动下，捕获放射性碘等有害污染物构成了一项重大挑战。多孔有机聚合物（POPs）是一种很有前途的高效吸附剂。在这项工作中，我们报道了通过亚胺缩合反应合成两种富氮持久性有机污染物BA-Mel和ba - tap。丰富的氮原子和苯环的存在为液相和气相中放射性碘的有效吸附提供了丰富的活性位点。在气相中，BA-Mel的碘吸收率为4.0 g g−1，而BA-TAPT的碘吸收率为4.7 g g−1。而在正己烷和模拟海水中，BA-Mel具有高孔隙结构、高含氮量、大表面积和优异的溶液分散性能，表现出优异的吸附能力。总的来说，这项研究强调，将富氮位点纳入POP是开发用于捕获碘的高效吸附剂的可行方法。
