In modern times, wastewater treatment is vital due to increased water contamination arising from pollutants such as nutrients, pathogens, heavy metals, and pharmaceutical residues. Polysaccharides (PSAs) are natural, renewable, non-toxic biopolymers used in the field of gas separation, liquid filtration, adsorption processes, pervaporation, proton exchange membranes. Since addition nanoparticles PSAs improves their sustainability strength, nanocomposite has gained significant attention for past decade. This review presents a comprehensive analysis PSA-based nanocomposites efficient treatment, focusing on adsorption, photocatalysis, membrane-based methods. It also discusses potential future applications, challenges, opportunities photocatalysis. Recently, have shown promise adsorbents biological-based systems, effectively removing metals that could hinder microbial activity. Cellulose-mediated successfully removed various wastewater, including dyes, oil, organic solvents, pesticides, Thus, PSA would support biological processes plants. A major concern discharge antibiotic wastes industries, posing environmental health risks. PSA-mediated bio-adsorbents, like clay polymeric hydrogel beads, efficiently remove antibiotics ensuring quality ecosystem balance. The successful use bio-adsorbents depends ongoing research optimize application evaluate impacts. Implementing these eco-friendly large scale holds great significantly reducing pollution, safeguarding ecosystems, protecting human health.

Efficient removal of heavy metals and other toxic metal pollutants from wastewater is essential to protect human health the surrounding vulnerable ecosystems. Therefore, significant efforts have been invested in developing practical sustainable tools address this issue, including high-performance adsorbents. In respect, within last few years, graphene-based aerogels/xerogels/cryogels (GBAs) emerged drawn attention as excellent materials for removing recovering harmful valuable different aqueous media. Such an upward trend mainly due features aerogel combined with properties graphene derivatives aerogel's network, GBAs' unique three-dimensional (3D) porous structure, high porosity, low density, large specific surface area, exceptional electron mobility, adjustable rich chemistry, remarkable mechanical features, tremendous stability. This review offers a comprehensive analysis fundamental aspects phenomena related application GBAs removal. Herein, we cover all types (bottom-up) synthesized GBAs, true microporous aerogels well 3D open-cell interconnected mesoporous macroporous aerogels, foams, sponges. Indeed, provide insights into understanding suitability such important by revealing mechanisms involved factors inducing controlling highly selective behavior these distinctive Besides conventional adsorptive pathways, critically analyzed ability electrochemically capture (i.e., electrosorption) their efficiency detoxification through reductive adsorption-reduction-readsorption). We also covered reusability aspect (GAs)-based adsorbents, which strongly linked outstanding stability efficient desorption captured metals. Furthermore, view numerous environmental benefits, development magnetically recoverable GAs highlighted. Moreover, shed light on potential scalable implementation evaluating performance continuous processes while highlighting versatility demonstrated remove multiple contaminants along Finally, provides readers accessible overview critical discussion major recent achievements regarding applications GAs-based adsorbents ions Along our recommendations suggestions future work new research directions opportunities, aims serve resource researchers field treatment inspire further progress towards next-generation expanding application.
