📝 Abstract
Biochar derived from agricultural residues has gained increasing attention as a sustainable material for soil improvement, carbon sequestration, and environmental remediation. In this study, biochar was produced from coconut husk through slow pyrolysis at 600 °C under oxygen-limited conditions and systematically characterized using Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), Brunauer–Emmett–Teller (BET) surface area analysis, and dynamic light scattering (DLS). FTIR analysis revealed the presence of oxygen-containing functional groups, including hydroxyl, carboxyl, and aromatic structures, indicating potential adsorption capability. SEM micrographs demonstrated a highly porous structure with irregular surface morphology favorable for contaminant adsorption and soil water retention. XRD patterns confirmed the presence of crystalline mineral phases such as quartz (SiO₂) and sylvite (KCl), along with amorphous carbon structures. BET analysis showed a specific surface area of 14.69 m² g⁻¹, indicating moderate porosity of the produced biochar. Dynamic light scattering analysis indicated particle sizes in the range of 2000–8000 nm, while zeta potential measurements (−17.2 mV) suggested moderate colloidal stability. These results demonstrate that coconut husk biochar possesses favorable physicochemical characteristics that make it a promising low-cost material for environmental remediation and sustainable agricultural applications.
