摘要

未经处理的放射性碘对环境和人类健康构成重大威胁,因此开发高效吸附放射性碘的吸附剂已成为当务之急。在这项研究中,我们创新地合成了两种离子自组装单晶材料:HBP-PyTS和VBp-PyTS。前者包括吡啶基有机阳离子和磺酸基阴离子,后者包括季铵基有机阳离子和磺酸阴离子。这些材料是用一种环境友好、简单、相对稳定的方法合成的。此外,它们由离子键组成,具有丰富的吸附位点,对碘的吸附非常有效。此外,对比两种材料的吸附能力,发现吡啶基团更有利于碘蒸气的吸附。HBP-PyTS材料在水和有机溶剂中均表现出优异的稳定性,在70 °C时对I2的吸附量为2.2 g g−1,在碘环己烷溶液中对碘的吸附量为51.2 mg g−1。HBP-PyTS表现出较高的吸附能力,这是由于电子转移复合物的机制和它们的比表面积和孔径。这表明该材料与其他材料相比具有优越的吸附性能,为开发新型碘吸附材料提供了一个有希望的策略。

Ionic self-assembled single-crystal for highly efficient capture of iodine
Untreated radioactive iodine poses a significant risk to both the environment and human health, so developing efficient adsorbents for the adsorption of radioactive iodine has become a top priority. In this study, we innovatively synthesized two ionic self-assembled single-crystal materials: HBP-PyTS and VBp-PyTS. The former comprises pyridine group organic cation and sulfonic acid group anion, while the latter contains quaternary ammonium group organic cation and sulfonic acid anion. These materials were synthesized using an environmentally friendly, simple, and relatively stable method. Besides, they were composed of ionic bonds and boasted abundant adsorption sites, which are highly effective at capturing iodine. Furthermore, a comparison of the adsorption capacity of these two materials reveals that the pyridine group is more conducive to the adsorption of iodine vapor. The HBP-PyTS material displayed excellent stability in both water and organic solvents, with an adsorption capacity of 2.2 g g−1 for I2 at 70 °C and an iodine adsorption in iodine-cyclohexane solution of 51.2 mg g−1. The HBP-PyTS displays a higher adsorption capacity due to the electron transfer complex mechanism and their specific surface area and pore size. This suggests that the material possesses superior adsorption properties compared to other materials, offering a promising strategy for developing a new type of iodine adsorption material.

期刊介绍: Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
