Herein, a hollow spherical pillar[5]arene-based polymer (P5-AO) adsorbent was synthesized. The P5-AO adsorbent was capable of effectively capturing uranium from simulated seawater (139.5 mg g) and real seawater (8.1 mg g). We also elucidated the uranium adsorption mechanism of P5-AO extended X-ray absorption fine structure (EXAFS). This study provides a novel direction for the development of uranium capture adsorbents.
在此，合成了一种基于空心球形柱[5]芳烃的聚合物（P5-AO）吸附剂。P5-AO吸附剂能够从模拟海水（139.5毫克/克）和实际海水（8.1毫克/克）中有效捕获铀。我们还通过扩展X射线吸收精细结构（EXAFS）阐明了P5-AO的铀吸附机制。本研究为铀捕获吸附剂的开发提供了新的方向。
