Realizing Direct Uranium Extraction from Seawater Using a Carboxyl‐g‐C 3 N 4 /CdS Hydrogel

solution. Furthermore, this hydrogel catalyst offers excellent stability, good recyclability, outstanding antifouling activity, and ease of separation, all of which are desirable for seawater uranium extraction. Finally, the test in real seawater demonstrates the successful extraction of uranium from seawater using the prepared hydrogel catalyst.
