“…These results prove that the pseudo-second-order and Ritchie models most accurately described the uranium adsorption process of GTA and AO-GTA. Besides, the chemisorption was the rate-determining step, 36 which may be caused by the complexation of surface multifunctional groups on the adsorbent.…”

“…[8][9][10][11] Biomass adsorbents, in virtue of the wide range of sources, low cost, green, and degradable properties, could be applied for the recovery of uranium and other heavy metal ions. [12][13][14][15][16][17][18] However, there are still some drawbacks of biomass adsorbents including their poor stability and mechanical properties that limit their potential in large-scale engineering applications being urgent to be improved to meet the practical adsorption application. [19][20][21][22] Hydrogels constructed by biomass material can form porous three-dimensional networks, which can not only improve their mechanical properties but also keep its structural integrity after absorbing water being advantageous for their separating and recycling from treated wastewater.…”

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.

In low- to middle-income communities, the lack of affordability of conventional sanitary products during menstrual cycles can cause psychological and health issues, ultimately affecting their quality of life. It is crucial to develop alternative products that are affordable and accessible to all while also promoting menstrual health and hygiene. Super absorbent polymers (SAPs) are a vital component in current disposable sanitary pads and nappies. However, these SAPs are often non-biodegradable and non-biocompatible. Therefore, the use of eco-friendly materials for the production of SAPs is gaining popularity in the hygiene industry, as it offers a means to reduce the carbon footprint and environmental impact associated with traditional SAPs made from non-renewable petroleum-based materials. SAPs made from polysaccharides often have naturally occurring antibacterial properties, making them appealing for commercial applications in sanitary products such as sanitary pads. In addition, the move toward reusable sanitary pads with antibacterial properties can significantly reduce waste generated by single-use products and prevent the growth of bacteria, improving the safety and hygiene of the product. Furthermore, computational modeling and artificial intelligence are now important tools in SAP synthesis, providing advantages such as predicting polymer properties, rationalizing synthesis pathways, and improving quality control. These tools can reduce synthesis costs by eliminating the need for trial-and-error approaches in polymer synthesis, ultimately promoting more affordable products for end users. Overall, these advancements in polymer synthesis and material design can help to create a more sustainable industry and promote menstrual hygiene and product accessibility to those who need it most.
