Researchers have reported a new material design aimed at improving uranium capture from wastewater, especially when uranium is present at very low concentrations. The work focuses on covalent organic framework, or COF, nanowires arranged horizontally on poly(amidoxime) fibers.

According to the study description, the team used an ion-coordination strategy to control how the COF nanowires grow and align on the fiber surface. That structure is intended to increase access to active binding sites and improve how efficiently the material can pull uranium out of contaminated water.

The study addresses a major environmental challenge: removing trace amounts of uranium before they can threaten aquatic systems and broader water security. Materials that can capture uranium effectively under dilute conditions are seen as especially important for treating industrial wastewater and protecting ecosystems.

The research was carried out by scientists at Northeast Normal University in Changchun, Jilin, China. Their findings point to a promising route for building fiber-based adsorbents that combine controlled nanostructures with practical uranium recovery performance.
