Nuclear power plays a pivotal role in the global energy supply. The adsorption-based extraction of uranium from seawater is crucial for the rapid advancement of nuclear power. The phosphorus nitride imide (PN) nanotubes were synthesized in this study using a solvothermal method, resulting in chemically stable cross-linked tubular hollow structures that draw inspiration from the intricate snowflake fractal pattern. Detailed characterization showed that these nanotubes possess a uniformly distributed five-coordinated nanopocket, which exhibited great selectivity and efficiency in binding uranium. PN nanotubes captured 97.34% uranium from the low U-spiked natural seawater (∼355 μg L −1 ) and showed a high adsorption capacity (435.58 mg g −1 ), along with a distribution coefficient, K d U > 8.71 × 10 7 mL g −1 . In addition, PN nanotubes showed a high adsorption capacity of 7.01 mg g −1 in natural seawater. The facile and scalable production of PN nanotubes presented in this study holds implications for advancing their large-scale implementation in the selective extraction of uranium from seawater.

“…The “defending” strategy is to prevent the attachment or adhesion of marine organisms on the adsorbent's surface. 253–259 Adsorbents with anti-adhesion properties are usually prepared by incorporating super-hydrophilic functional groups, which reduce the interactions between the adsorbents and microorganisms, and then prevent their adhesion onto the surfaces. Compared with the potential risk of secondary pollution caused by dead bacteria produced by active sterilization methods, passive defence methods represent a class of more environmentally friendly strategies.…”

“…Therefore, the construction of hydrogels has become a promising method to improve the properties of biomass material, and biomass hydrogel adsorbents have been well-known for recycling heavy metal from polluted effluent. [29][30][31][32][33][34][35][36] There are two kinds of methods to construct hydrogels including chemical cross-linking and physical crosslinking. [37][38][39] Most of the biomass hydrogel adsorbents studied at present are prepared by chemical cross-linking of biomass raw material using toxic chemical crosslinkers, which could result in secondary environmental pollution due to the difficulty of removing the residual cross-linkers thoroughly from hydrogels.…”

Recently, double‐network or multiple‐network hydrogel constructed by physical methods has been considered a green method to improve the comprehensive properties of biomass hydrogel. Herein, a novel physically cross‐linked hydrogel with multiple network of gellan gum/chitosan/calcium ion (GG–CS–Ca) was constructed by self‐assembly to accomplish the synergistic improvement of mechanical strength and uranium adsorption property compared to adsorbents GG–Ca and carboxymethyl konjac glucomannan/GG–Al originated from gellan gum previously prepared. Moreover, the driving mechanism of self‐assembly of GG–CS–Ca was deduced by 13C solid state nuclear magnetic resonance spectroscopy (13C‐SSNMR), rheological analysis, and phase transition analysis. The results indicated electrostatic interaction was dominant during the self‐assembly of GG–CS–Ca. The self‐assembly mechanism was also illustrated by investigating the x‐ray photoelectron spectrometer (XPS) combined with the analysis of the phase transition process. Comprehensively, the self‐assembly constructed GG–CS–Ca hydrogel network contained three kinds of network including the GG–CS network constructed by electrostatic action of protonated CS with negative charged GG, the GG–Ca network constructed by ionic cross‐linking of COO− in GG and Ca2+, and the GG network formed after the phase transformation of GG hot sol by cooling. It explored a new method for constructing biomass‐based physical hydrogels with both favorable mechanical strength and uranium adsorption capacity in uranium removal.Highlights A novel physically cross‐linked hydrogel (GG–CS–Ca) with multiple network was constructed by self‐assembly. The GG–CS–Ca hydrogel accomplished the synergistic improvement of mechanical strength and uranium adsorption properties. The self‐assembly mechanism of constructing the GG–CS–Ca hydrogel network contained three aspects. The electrostatic interaction was the dominant action during the self‐assembly of GG–CS–Ca.
