Sugarcane bagasse as a strategy for the sustainable development of magnetic adsorbents for dye remediation
This study aimed to evaluate sugarcane bagasse as a precursor for the synthesis of magnetic carbonaceous material (MC) produced at 230 °C via hydrothermal carbonization, followed by an activation process with KOH (1:2 and 1:4; m:m) at 700 °C under a nitrogen atmosphere (MAC). The study assessed the structure, texture, and adsorption capacity of MC and MAC for the dye methylene blue (MB). FTIR analysis was performed to investigate the structural properties, while BET and BJH analyses were conducted to determine the specific surface area and pore volume.
