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.

In this study, fig branch biochar (FBB) was modified by chitosan to improve the Cd2+ adsorption performance from an aqueous solution. The surface area, pores, and functional groups of chitosan-modified (CMFBB) were characterized DTG-TGA, BET, SEM-EDS, FTIR, XRD. addition, impact various conditions on Cd analyzed, including dosage, initial pH, concentration, temperature, reaction time, coexisting cations. kinetics, isotherms, practical applications also investigated. Under optimized pH 6, adsorbent dose 2 g L-1, time 90 min, concentration 100 mg 25 °C, capacity 62.25 g-1, representing a 78.26% increase compared FBB. data for CMFBB found be well-described pseudo-second-order kinetic Langmuir isothermal models, indicating that monolayer chemical process occurred. spontaneous endothermic process, cations exerted negligible influence process. After five adsorption-desorption cycles, maintained efficiency 92.3%, demonstrating excellent regeneration capability. quantification mechanisms suggested physical adsorption, cation exchange, precipitation, complexation, π-π interactions accounted 3.70, 2.50, 33.04, 58.76, 2.0% total adsorbed in CMFBB, respectively. Compared with FBB, level increased 26.52% complexation. This work implies has great potential as effective absorbent treating polluted water.
