abstract = {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.}
