“…Because Nano-celluloses in their natural state do not conform to greater adsorptive capacities, future research should focus on enhancement tactics that contribute to a more efficient and adaptable composite [21]. Surface functionalization can improve the binding properties of NC-based biosorbents, but this may increase the overall cost of the technique, equating it to the price of commercial adsorbents such as ion exchange resins, molecular sieve carbon, activated alumina, or zeolites, among others [154].…”

Rapid industrialization and unplanned urbanization have significantly increased environmental pollution. These human behaviors have resulted in massive waste discharges into the environment. As a result, organic and inorganic contaminants, including heavy metals, have accumulated in surface and groundwater. Heavy metals are highly carcinogenic and deadly. Heavy metal removal from drinking water has always been difficult. Conventional water treatment procedures could be more efficient, wasteful of energy, and generate massive amounts of harmful waste. In this initiative, researchers created a bio-based adsorption technology for removing heavy metal ions from polluted water. Nano celluloses (NCs) as biosorbents have sparked considerable attention due to their unique properties, such as the presence of several -OH groups on their surface, allowing the insertion of chemical moieties, a substantial specific surface area, strong mechanical properties, recyclability, and biodegradability. This review paper goes into great detail regarding the ways of producing Nano cellulose and its essential qualities. Many factors influence the use of NC- based adsorbents in water treatment systems, including synthesis pathways, functionalization of the surface, specific surface area, regeneration capacity, and reusability. Recent advances in bio-sorbent synthesis have prompted using bio-derived NC-based adsorbents in water treatment methods. This study also demonstrates that utilizing the potential for agricultural wastes, specifically sugarcane bagasse (SCB), as a precursor for Nano celluloses represents a sustainable approach, namely the conversion of low-value waste into a specific high-value product and its use in wastewater treatment.

“…[27,28] Therefore, the synthesis of adsorbents based on nanoparticles with high surface area, high porosity, and adsorption capacity, as well as the ability to separate quickly and easily is essential. According to the recent advances in nanotechnology, it is possible to synthesize multifunctional advance nanomaterials and to apply them in various application areas including optics, [29] energy, [30,31] catalyst, [32][33][34][35][36][37] nano-chemistry, [38][39][40][41][42] food safety, [43,44] sensors, [45,46] environment, [47,48] etc. One of these nanomaterials is the natural polymers and SiO 2 nanoparticles that have high porosity and surface area.…”

The present study performed synthesis and characterization nanocomposite based polysaccharide Chitosan/Agar and Chitosan/Agar/SiO2 nanoparticles as adsorbents for remove amoxicillin and naproxen as the pharmaceuticals from an aqueous solution. The structure and morphology of nanocomposite were investigated using X‐ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X‐ray spectroscopy (EDX), Fourier‐transform infrared spectroscopy (FTIR), Transmission electron microscopy (TEM), Field Emission Scanning Electron Microscopes (FE‐SEM) and Dynamic light scattering (DLS). The removal performance of the Chitosan/Agar and Chitosan/Agar/SiO2 nanoparticles nanocomposite as adsorbent for removing amoxicillin and naproxen as sample of pharmaceutical industry effluents in aqueous solutions was investigated under different influence factors, including contact time, initial concentration, pH conditions and temperature. The maximum adsorption removal for amoxicillin with Agar/Chitosan and Agar/Chitosan/SiO2 nanocomposite at initial concentrations of 20 mg/l was 97.85 % and 87.9 %, respectively. With increasing temperature from 10 to 30°C, the removal efficiency for naproxen for both adsorbents is 99 %. The prepared nanocomposites showed good performance in adsorbing naproxen and amoxicillin. The maximum adsorption efficiency of nanocomposite was 99 % and 91 % for naproxen and amoxicillin, respectively. The optimum condition for pharmaceuticals removal by the nanocomposite was initial concentration: 20 mg/l, adsorbent dose: 0.05 g, contact time: 10 min, and pH=6.
