Abstract Extracting uranium from the ocean is considered a promising solution for meeting nuclear fuel consumption. To date, porous adsorbents fabricated with polyamidoxime (PAO), particularly macroporous PAO hydrogels, have demonstrated exceptional potential capture natural seawater. Herein, novel hydrogel developed via well‐designed wax‐casting method. The wax‐casted (WMPAO) particles are subsequently encapsulated in alginate‐polyacrylic acid (A‐PAA) beads. obtained A‐PAA@WMPAO beads exhibit high q max of 687.4 mg‐U/g‐Ads. and show good adsorption capacity 8.23 mg g −1 toward simulated Additionally, shows reusability 31.2% reduction after five consecutive adsorption‐desorption cycles. Furthermore, displays satisfactory extraction efficiencies 95.9–99.5% U‐spiked coastal seawater 10 days adsorption, achieving capacities ranging 207.5 to 3963.2 µg . Particularly, utilization 4 beads, 4.79 L within 15 achieved. These results comprehensively demonstrate significant
