摘要

这项研究成功制备了一种用于铀捕获的石墨烯/羧甲基纤维素/聚（氨基肟）气凝胶，命名为 GCPA。令人兴奋的是，GCPA 表现出卓越的机械性能（320 千帕）。此外，即使经过 6 次吸附-解吸循环，GCPA 的吸附率仍保持在 90% 以上。吸附机理分析结果表明，GCPA 主要通过静电吸引、粒子内扩散和配位吸附铀。值得一提的是，GCPA 在弱碱性环境中对铀保持着良好的吸附能力。而且，即使在有竞争离子存在的情况下，GCPA 对铀也具有优异的选择性。研究结果表明，GCPA 可用于从天然海水中提取铀。

Self-assembled fabrication of robust and durable graphene-based composite aerogel for selective uranium capture

This work successfully prepared a graphene/carboxymethyl cellulose/poly(amidoxime) aerogel named GCPA for uranium capture. Excitingly, GCPA exhibits superb mechanical properties (320 kPa). Additionally, the adsorption rate of GCPA remained above 90% even after 6 adsorption–desorption cycles. The results of the adsorption mechanism analysis show that GCPA adsorbed uranium mainly through electrostatic attraction, intraparticle diffusion, and coordination. It is worth mentioning that GCPA maintains good adsorption capacity for uranium in weakly alkaline environments. And GCPA has exceptional selectivity for uranium even in the presence of competing ions. Results show that GCPA is expected to be utilized in uranium extraction from natural seawater.
