Activated carbon was be produced from Canarium schweinfurthii seed by physical and chemical processes. Acetic acid was used as alternative chemical at various concentrations (30 – 60%). The reaction conditions were optimized at temperature range 400 – 600 0C and time interval of 20 – 60 minutes. The raw atile seed and carbonized charcoal were characterized using parameters like bulk density, percentage yield, moisture content, ash content and percentage of carbon. The uncarbonized atile seed has a bulk density of 0.4348, percentage yield 93 %, moisture content 4.7 %, ash content 2.3 % and percentage of carbon 93 %, while the carbonized charcoal at temperature range of (400 – 600 0C) has a bulk density of (0.4115 – 0.4312 g/cm3), percentage yield (80.82 – 86.48 %), moisture content (13 – 17 %), ash content (6 – 2 %) and percentage of carbon of (74.005 – 84.510 %). The activated carbon was further used to decolourize dye effluent. The experimental data were analyzed using Langmuir, Freundlich and Dubinin-Radushkevich isotherms. After optimization, the activated carbon was structurally analyzed using Fourier-transform infrared spectroscopy (FTIR), Scanning electron microscope (SEM), Brunauer-Emmett-Teller (BET) and X-ray diffraction (XRD).
