The cover picture shows the passive adsorption of uranium and vanadium from a natural seawater environment using amidoxime‐based polymeric adsorbents. Amidoxime‐based adsorbents have been demonstrated as promising adsorbents for the extraction of uranium from seawater. However, the strong competition from vanadium over uranium for amidoxime adsorption sites limits the adsorption performance of polyamidoxime adsorbents in natural seawater. Temperature has a very strong influence on uranium adsorption capacity in natural seawater. Thermodynamic calculations suggest that the adsorption of U(VI) is highly endothermic, while the adsorption of V(V) only has minimal temperature sensitivity, making warm waters favorable for the extraction of uranium.
