Abstract

Acid Mine Drainage (AMD) presents significant environmental challenges due to its low pH levels and high concentrations of heavy metals, such as iron (Fe), which pose serious risks to both ecosystems and human health. This research investigates the synthesis and preliminary characterization of activated carbon biosorbents derived from oil palm empty fruit bunches (OPEFB), enhanced with alumina (Al₂O₃) and chitosan. The OPEFB biomass was carbonized at 600°C in an anaerobic environment and processed to achieve a uniform particle size of 200 mesh. SEM characterization revealed non-uniform particle distribution and agglomeration, which impacted pore development. FTIR analysis identified functional groups like silanol, hydroxide, and siloxane, demonstrating the material's adsorption potential. BET analysis indicated a specific surface area of 6.177 m²/g and a pore volume of 1.567 cm³/g. Despite the relatively modest surface area, these results provide a basis for further improvements, such as optimizing pore structure and adsorption capabilities. The study underscores the potential of alumina-chitosan modified OPEFB-based activated carbon as an efficient, cost-effective, and sustainable approach for AMD remediation, particularly for Fe removal.
