摘要：This study was conducted to determine the physical characteristics of activated carbon prepared from durian shell in varied heating durations from 10 min to 30 min and activation temperatures of 400°C and 500°C. Durian shells have been characterized in term of ultimate and proximate analysis, chemical composition and thermal behaviour with a view to be used as activated carbon precursor. Durian shell activated carbon was prepared by impregnating 10g of sample in 10% (v/v) concentration of phosphoric acid for 24 h, followed by carbonization at 400°C and 500°C with different heating durations under nitrogen atmosphere. The results showed that various treatment conditions affect the percentage of yield, BET surface area, micropore volume, and average pore diameter. The highest surface area (SBET) 1024 m2/g was obtained at 500°C and 20 min of heating duration with 63% of yield and 0.21 cm3/g micropore volume.
