The development of practical techniques for trapping radioactive iodine (I2) is crucial to the safe development of nuclear power. Herein, we reported a functionalized porous metal–organic framework (MOF), [Zn3(ABTC)1.5(4-Hpich)(H2O)3]·10H2O (Zn-ABTC) (H4ABTC = 2,2′,5,5′-azobenzenetetracarboxylic acid, 4-Hpcih = 4-pyridinecarbaldehyde isonicotinoyl hydrazone), with azo double and amide groups. The adsorption experiments showed that Zn-ABTC exhibited excellent adsorption capacity for volatile I2 (2.02 g g–1) and I2 cyclohexane solution (526 mg g–1) due to the introduction of nitrogen and oxygen active sites into the framework. Furthermore, Zn-ABTC has excellent recoverability and stability, retaining its adsorption capacity, even after five cycles. The spectroscopic analysis revealed the multiple interactions between the I2 molecules and azo double as well as amide groups. This work provides a rational strategy for constructing functional MOF materials for I2 adsorption.

具有偶氮双基团和酰胺基团的功能化金属有机框架可实现高效碘捕获
开发捕获放射性碘（I 2 ）的实用技术对于核电的安全发展至关重要。在此，我们报道了一种功能化多孔金属有机骨架（MOF），[Zn 3 (ABTC) 1.5 (4-Hpich)(H 2 O) 3 ]·10H 2 O ( Zn-ABTC ) (H 4 ABTC = 2， 2',5,5'-偶氮苯四甲酸，4-Hpcih = 4-吡啶甲醛异烟酰腙），具有偶氮双基和酰胺基。吸附实验表明，由于在骨架中引入了氮和氧活性位点，Zn-ABTC对挥发性I 2 (2.02 gg –1 )和I 2环己烷溶液(526 mg g –1 )表现出优异的吸附能力。此外，Zn-ABTC具有优异的可恢复性和稳定性，即使在五个循环后仍能保持其吸附能力。光谱分析揭示了I 2分子与偶氮双以及酰胺基团之间的多重相互作用。这项工作为构建用于I 2吸附的功能性MOF材料提供了合理的策略。
