Novel high-efficient adsorbent based on modified gelatin/montmorillonite nanocomposite for removal of malachite green dye

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Jan. 12, 2024

Abstract Shortage of drinking water has gained potential interest over the last few decades. Discharged industrial effluent, including various toxic pollutants, to surfaces is one most serious environmental issues. The adsorption technique become a widely studied method for removal specifically synthetic dyes, from wastewater due its cost-effectiveness, high selectivity, and ease operation. In this study, novel gelatin-crosslinked-poly(acrylamide- co -itaconic acid)/montmorillonite (MMT) nanoclay nanocomposites-based adsorbent been prepared removing malachite green (MG) dye an aqueous solution. Modified gelatin nanocomposites were synthesized using free-radical polymerization in presence absence MMT. Various analytical instrumentation: FTIR, FESEM, XRD, TEM techniques used elucidate chemical structure surface morphology samples. Using batch experiment, Langmuir isotherm model showed that modified nanocomposite had maximum capacity 950.5 mg/g 350 mg/L MG at pH 9 within 45 min. Furthermore, regeneration study good recyclability obtained through four consecutive reusable cycles. Therefore, fabricated attractive elimination solutions.

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

Royal Society Open Science, Journal Year: 2024, Volume and Issue: 11(5)

Published: May 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.
