Abstract
A series of activated carbons were prepared from oil palm trunk impregnated with varying concentration of phosphoric acid using a two-steps activation procedure: carbonization at 200°C for 15 minutes followed by activation at 500°C for 45 minutes. Physical and chemical characterizations such as iodine number, ash content, moisture content, pH, percent yield and methylene blue adsorption determination were performed. Percent yield of activated carbon ranged from 28.3% to 55.6%, depending on the concentration of phosphoric acid. The activated carbons have pH values ranging from 6.32 to 5.14, ash content ranging from 0.4% to 3.8%, moisture content in the range of 2.4% to 7.33%, iodine number ranging from 187.96mg/g to 492.76mg/g and methylene blue adsorption capacity ranging from and 80mg/g to 855mg/g.
