Cellulosic biomass-based sustainable hydrogels for wastewater remediation: Chemistry and prospective

Despite several technological improvements and achievements, wastewater treatment remains a serious issue internationally. Toxins in pose significant threat to human health if left untreated. Due macro-porous structure different surface functionalization, cellulose biomass-based hydrogel is the most traditional adsorbent for removing harmful ions from wastewater. Recently, introduction of new derived materials have demonstrated their competitiveness removal ions. Numerous exceptional qualities better define this promising material, including high mechanical strength, large area chemical inertness. This paper discusses development status, preparation modification methods composites created by various (graphene, fly ash, graphene oxide bentonite) which evaluates research existing challenges water treatment.
