AB - Biochar materials possess a porous structure suitable for adsorption applications. However, effective modifications are required to enhance their adsorption performance. This study developed a high-performance biochar (HBC) derived from sugarcane bagasse. Characterization by XRD, SEM, EDS, BET, XPS and FT-IR revealed that the sugarcane bagasse-derived biochar was fabricated successfully by a pyrolysis/acid-washing strategy. The acid-washing operation efficiently etched the iron-based component of biochar precursor that was previously synthesized by pyrolysis processing, promoting the achieved biochar exposing more accessible active sites that include C = O, C = C COO⁻, C-N and -OH functional groups. These functional groups significantly enhanced the adsorption capacity for MB through mechanisms including electrostatic interaction, π–π interaction, electrostatic assistance and hydrogen bonding effect. The adsorption isotherm for MB onto HBC followed the Langmuir model, while the adsorption kinetics adhered to the pseudo-second-order equation, indicating chemisorption as the dominant process. The HBC achieved a high adsorption capacity of 476.55 mg·g⁻¹ while maintaining an impressive MB removal efficiency of 95.31%. This research offers a new solution for the disposal and utilization of agricultural waste and holds significant practical importance for developing low-cost, environmentally friendly adsorbents.
