Summary: In this study, hydrogels with photothermal conversion properties were prepared using graphene oxide (GO) and polyacrylamide/polyacrylic acid (PAM/PAA) for efficient uranium extraction from seawater. The addition of zwitterionic 2-methacryloyloxy ethyl phosphorylcholine (MPC) in the hydrogel improved its antibacterial properties. The adsorption capacity of the hydrogel under light conditions was higher than that under dark conditions, and the adsorption process was modeled using Langmuir and pseudo-second-order models. The hydrogel exhibited good repeatability and stability after multiple adsorption-desorption cycles, making it a promising candidate for uranium extraction from seawater.

Summary: In this study, high efficiency uranium extraction was achieved under ultra-low cell voltage (-0.1 V) in seawater with 20 ppm UO2(NO3)(2) solution by coupling electrochemical mediated Fe-II/Fe-III redox and uranium extraction. The adsorption capacity and extraction efficiency of NRI after electrochemical uranium extraction (EUE) reached 452 mg/g and 99.1 %, respectively. Quasi-operando/operando characterization technologies were used to clarify the mechanism of EUE and it was revealed that continuously regenerating Fe-II active sites by electroreduction significantly enhanced the property of EUE.

Summary: A chitosan-based porous composite adsorbent was prepared with phosphoric acid, amidoxime, and quaternary ammonium groups to enhance the adsorption rate and competitive uranium-vanadium adsorption. PACNC exhibited a maximum uranium adsorption capacity of 962.226 mg g-1 at 308 K and pH = 7, with an adsorption rate constant 2.38 times higher than that of ACNC. The adsorption equilibrium time was reduced to 50 minutes with PACNC compared to 300 minutes with ACNC. PACNC also showed excellent recycling performance and maintained stable adsorption capacity after five cycles. The results suggest that phosphorylation improves the competitive adsorption of uranium-vanadium and uranium adsorption rate.

Summary: Combination of ligand complexation and photocatalytic reduction has been applied to uranium enrichment using porous framework-based photocatalysts, but their practical applicability is limited by poor photocatalytic activity and low adsorption capacity. This study presents a new method to prepare atomically dispersed Cu implanted UiO-66-NH2 (Cu SA@UiO-66-NH2) photocatalysts via ligand-assistant iced photocatalytic reduction route, which improves the photocatalytic activity and adsorption capacity for uranium from natural seawater. The Cu SA@UiO-66-NH2 adsorbents show superior antibacterial ability and improved photoreduction conversion of U(VI) to insoluble U(IV), resulting in a high uranium sorption capacity of 9.16 mg-U/g-Ads. This study provides new insights for enhancing uranium uptake by designing SA-mediated MOF photocatalysts.

Summary: In this study, Fe3O4 nanoparticles were incorporated into amidoxime-functionalized Ti3C2 to form a novel magnetic MXenes composite (Fe3O4@Ti3C2-PDA/OA) for the removal of radionuclides from simulated radioactive wastewater. The adsorption performance of the composite was investigated under different conditions, and the results showed that Fe3O4@Ti3C2-PDA/OA had much higher adsorption capacity for U(VI) and Th(IV) compared to traditional adsorption materials. The mechanism of adsorption was found to be through complexation of hydroxyls and amidoxime groups on the surface of the composite with U(VI) and Th(IV). This study demonstrates the potential of MXenes-based composites in the remediation of radioactive ions.
