Abstract
Abstract Functionalized amidoxime [AO, R−C(NH 2 )═N(OH)] is widely used for uranium extraction from seawater, but increasing the effective functional sites for high AO utilization in adsorbents remains challenging. This study introduces a hydrogen bond reconstruction strategy to enhance uranium extraction efficiency of AO‐modified polyacrylonitrile (PAN) fibers by blending with polyvinyl alcohol (PVA). The PAN/PVA fibers are synthesized via electrospinning, followed by amidoximation on PAN to prepare PAN‐AO/PVA adsorbents. These materials can extract uranyl ions from the uranyl‐carbonate complex in seawater, achieving an adsorption capacity of 21.0 mg g⁻¹ under simulated seawater conditions with 330 ppb…
