This study introduces a new strategy for the environmentally friendly catalytic degradation of Reactive Red 24 (RR24) dye using sunlight. We developed cost-effective quaternary nanocomposite by immobilizing sodium alginate biopolymer over bioengineered Co-Zn-Ce nanoparticles, forming an SA@Co–Zn–Ce (where SA means alginate). composite also demonstrated exceptional antioxidant potential approximately 89%, attributed to synergistic effect and green-synthesized Co–Zn–Ce nanoparticles (biosynthesized Ocimum sanctum leaf extract as reducing agent). Scanning electron microscopy revealed grain sizes 28.6 nm NPs 25.59 nanocomposites (NCs). X-ray diffraction showed particle 16.87 15.43 nm, respectively. exhibited zeta 1.99 mV, whereas alginate-anchored −7.99 mV. indicated entrapment negatively charged ions from alginate, altering surface charge characteristics enhancing photocatalytic RR24. Dynamic light scattering average size 81 NCs, with larger due influence water molecules in colloidal solution affecting hydrodynamic diameter measurement. The NCs CO2 adsorption capacity 3.29 mmol/g at 25 °C 4.76 40 °C, indicating temperature-dependent variations capabilities. specific area oxide NPs, measured Brunauer–Emmett–Teller (BET) analysis, was found be 167.346 m2/g, 24.14 m2/g. BJH analysis pore diameters 34.60 Å 9.26 NCs. Although immobilization on did not increase sites porosity composite, evidenced N2 adsorption–desorption isotherms, still high efficiency

Adsorbents derived from bamboo, such as biochar, charcoal, activated carbon, and chemically modified are recognized for their efficiency cost-effectiveness in removing heavy metals water. Despite this, there remains a gap applying bamboo-based adsorbents treating metal-contaminated water sources, particularly regarding physicochemical properties, adsorption mechanisms, modifications. This review highlights the influence of factors specific surface area, pore distribution, pH, cation exchange capacity, elemental composition, functional groups on ability bamboo to adsorb metals. It also discusses recent advancements enhancing properties through physical chemical modifications examines how variables like adsorbent dosage, temperature, initial concentrations cations, affect metal removal. The categorizes mechanisms into complexation, adsorption, electrostatic interaction, ion exchange, precipitation, redox effect. While have shown higher sorption capacity laboratory settings, is need more comprehensive studies optimize performance, scalability, real-world applications.
