Amidoxime-functionalized hydrogels are one of most promising adsorbents for high-efficiency uranium (U) extraction from seawater, but bioadhesion on their surface seriously decreases adsorption efficiency and largely shortens service life. Herein, a semi-interpenetrating zwitterion–poly(amidoxime) (ZW-PAO) hydrogel was explored through introducing PAO polymer into poly [3-(dimethyl 4-vinylbenzyl amino) propyl sulfonate] (PDVBAP) polyzwitterionic (PZW) network via ultraviolet (UV) polymerization. Owing to the anti-polyelectrolyte effect PZW network, this ZW-PAO can provide excellent super-hydrophilicity in seawater U-adsorption seawater. Furthermore, had outstanding anti-biofouling performance both highly enhanced relatively long working life natural As result, during only 25 days (without filtering bacteria), U-uptake amount reach 9.38 mg/g its average rate 0.375 mg/(g∙day), which is among reported adsorbents. This work has U-recovery will inspire new strategy U-adsorbing materials.
