Carbon nanomaterials are promising adsorbents for dye removal from wastewater also due to their possible surface functionalization that, in principle, can increase the adsorption rate and provide regeneration. To investigate real advantages of functionalization, we synthesized characterized through IR, TGA, TEM, XPS DLS measurements a multi-walled carbon nanotube (MWCNT) derivative bearing benzenesulfonate groups (MWCNT-S). The obtained material demonstrated have good dispersibility water better capability adsorb methylene blue (MB) compared pristine MWCNT adsorbent. Adsorption kinetic studies showed very fast process, with constant significantly higher respect not only that unfunctionalized adsorbent but those widely used activated carbons. Moreover, capacity MWCNT-S is more than doubled insoluble adsorbent, thanks derivatives, providing larger available surface, electrostatic interactions between cationic MB anionic sulfonate groups. Additionally, reversibility ionic disclosed possibility release adsorbed pollutant competition salts, regenerating recovering dye. Indeed, by treating 1 h M NaCl, regeneration 75% was obtained, demonstrating validity this strategy.

Advancements in application of modified biochar as a green and low-cost adsorbent for wastewater remediation from organic dyes

Royal Society Open Science, Год журнала: 2024, Номер 11(5)

Опубликована: Май 1, 2024

Synthetic organic dyes, which are resistant to biodegradation, pose a notable health risk, potentially leading cancer and respiratory infections. Researchers have addressed this concern by exploring physicochemical methods remove dyes from wastewater. A particularly promising solution involves modified biochar adsorbents, demonstrate high efficiency in dye removal. Biochar, charcoal-like material derived biomass pyrolysis, offers advantages such as low cost, eco-friendliness, reusability. Beyond its role sustainable soil remediation, proves effective removing wastewater after undergoing physical or chemical modification. Acid–base activation metal–heteroatom impregnation enhances biochar's adsorption capacity. This comprehensive review examines the attributes of biochar, common for production modification, impacts raw materials, pyrolysis temperature, heating rate residence time. It further elucidates mechanism removal assessing factors influencing efficiency, including feedstock, pH, particle size, initial concentration, dosage reaction explores challenges, opportunities, reusability regeneration treating also discusses recent advances using adsorption-based biochar. The ultimately advocates enhancing performance through post-modification.

Recent advances in polymer nanocomposites for the adsorptive removal of toxic azo dyes from water

Discover Water, Год журнала: 2025, Номер 5(1)

Опубликована: Апрель 14, 2025

Abstract Adequate wastewater treatment technologies are essential for addressing toxic dyes’ environmental pollution and health hazards. Azo dyes which contain one or more azo bonds widely used in the textile. However, they known to be carcinogenic, mutagenic, highly human health. Traditional treatments methods, such as coagulation, flocculation, biological treatment, often fail eliminate dye molecules due their complex structures strong chemical stability. Therefore, there is a need advanced solutions. Polymer nanocomposites have emerged promising alternative, offering high surface area, tunable properties, exceptional adsorption capacities. This review describes recent reports on synthesis, characterization, application of polymer removal, incorporating key findings remarkable capacity gelatin nanocomposite (950.5 mg/g). most studies were synthetic solutions with limited validation real industrial effluents. paper also future research development scalability, cost analysis, biodegradability practical use. aims guide toward effective adsorbent, eco-friendly, scalable removal.
