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.

The adsorption properties of 2,4-Dichlorophenoxyacetic acid (2,4-D) onto biochar, obtained through HCl-assisted hydrothermal carbonization process Vateria indica fruits (VI-BC), were extensively studied using traditional and statistical physics approaches. investigations encompassed kinetics, equilibrium, thermodynamics studies. Subsequently, the Hill model was employed to interpret mechanism. Also, artificial neural network (ANN) adaptive neuro-fuzzy inference system (ANFIS) machine learning tools successfully data wherein both models had high prediction potential (R
