摘要

有效可逆吸附剂是处理核污染的有效手段之一。本文通过Friedel-Crafts烷基化反应合成了三种含二苯基磷酸盐的超交联聚合物（TP-HCPs）。这些聚合物具有显著的特性，包括高比表面积，微孔和介孔形态，以及优异的热稳定性和化学稳定性。值得注意的是，TP-HCP-3具有702.33 m2 g−1的比表面积和519 wt%的最大碘蒸气捕获能力，优于大多数其他多孔吸附剂。TP-HCP-3对碘的去除率达到96.8%。TP-HCPs对碘的吸附过程以化学过程为主，并表现出在非均质表面上的多层吸附特征。此外，聚合物具有显著的可回收性，即使经过5次循环，其吸附容量仍保持在84%以上。这些发现突出了TP-HCPs作为放射性碘废物的有效吸附剂的潜力。图形抽象

Diphenyl phosphate hyper-cross-linked porous polymers for effective iodine capture

Effective and reversible adsorbents are one of the effective means of dealing with nuclear pollution. Herein, three diphenyl phosphates-containing hyper-cross-linked polymers (TP-HCPs) have been synthesized through Friedel-Crafts alkylation reactions. These polymers exhibited remarkable characteristics, including high specific surface areas, microporous and mesoporous morphologies, as well as exceptional thermal and chemical stability. Notably, the TP-HCP-3 possesses a specific surface area of 702.33 m² g^− 1 and exhibits a maximum iodine vapor capture capacity of 519 wt%, outperforming most other porous adsorbents. Furthermore, the removal efficiency of TP-HCP-3 for iodine from aqueous solutions reached 96.8%. The adsorption of iodine processes by TP-HCPs were predominantly chemical processes and exhibited characteristics of multilayer adsorption on heterogeneous surfaces. Additionally, the polymers exhibited remarkable recyclability, maintaining an adsorption capacity above 84% even after 5 cycles. These findings highlight the potential of TP-HCPs as efficient adsorbents for radioactive iodine waste.

期刊介绍： The Journal of Porous Materials is an interdisciplinary and international periodical devoted to all types of porous materials. Its aim is the rapid publication of high quality, peer-reviewed papers focused on the synthesis, processing, characterization and property evaluation of all porous materials. The objective is to establish a unique journal that will serve as a principal means of communication for the growing interdisciplinary field of porous materials. Porous materials include microporous materials with 50 nm pores. Examples of microporous materials are natural and synthetic molecular sieves, cationic and anionic clays, pillared clays, tobermorites, pillared Zr and Ti phosphates, spherosilicates, carbons, porous polymers, xerogels, etc. Mesoporous materials include synthetic molecular sieves, xerogels, aerogels, glasses, glass ceramics, porous polymers, etc.; while macroporous materials include ceramics, glass ceramics, porous polymers, aerogels, cement, etc. The porous materials can be crystalline, semicrystalline or noncrystalline, or combinations thereof. They can also be either organic, inorganic, or their composites. The overall objective of the journal is the establishment of one main forum covering the basic and applied aspects of all porous materials.
