摘要
脒肟功能化聚合物吸附剂在从海水中提取铀方面引起了极大的兴趣。然而，目前的接枝聚合方法耗时长（2-6 小时）、浪费试剂，因此并不经济。本文采用简单、快速、低成本的表面光接枝技术，制备了基于低成本聚丙烯熔喷非织造布（MBF）的脒肟功能化吸附剂，可节省 80% 以上的试剂，并将接枝时间缩短至 3 分钟。当 AN 与 AA 的单体比为 8 : 2 时，最大铀吸附量为 400 mg g-1。此外，我们还发现这些吸附剂既可重复使用，也可直接焚烧以回收铀。光固化技术在低成本、连续工业化生产铀吸附材料方面具有巨大潜力。
Toward a low-cost uranium-adsorbing material based on nonwoven fabrics and photografting technology†
Amidoxime-functionalized polymeric adsorbents have attracted great interest for uranium extraction from seawater. However, the current graft polymerization method is time-consuming (2–6 h), wasteful in reagent, and hence not economical. Here, amidoxime-functionalized adsorbents based on low-cost polypropylene melt-blown nonwoven fabric (MBF) are produced by a simple, fast and also low-cost surface photografting technology, by which more than 80% of reagents can be saved and grafting time can be reduced to 3 min. The fabricated adsorbents retain their mechanical properties and exhibit excellent uranium adsorption properties, with a maximum uranium adsorption capacity of 400 mg g−1 when the monomer ratio of AN to AA is 8 : 2. Moreover, we showed that the adsorbents could be either reused or simply incinerated for uranium recovery. The photografting technology has great potential for low-cost, continuous industrial production of uranium-adsorbing material.
Keywords: Uranium extraction from seawater; Amidoxime; Nonwoven fabric; Surface photografting.
