Abstract:
Activated Carbon is the product of charcoal impregnation process that has a higher adsorption capacity and more benefits than regular charcoal. Therefore, this study aims to produce activated carbon that meet standard. Carbonization (pyrolysis) of carbon obtained from Gmelina (Gmelina Aboreal) wood was achieved at temperature of 480 °C for 2 hours. The carbonized carbon was activated via the chemical activation process using HNO3. Characterization of Iodine Number, Ash content Moisture content, Bulk Density, Free Carbon Brunauer-Emmet- Teller (BET), X-Ray Diffraction was conducted. The result obtained from carbonized Gmelina Nitric Acid Activated Carbon was found to have iodine number of 1050 mg/g, Ash Content of 11%, Moisture Content of 8.2%, Bulk Density of 0.5%, Free Carbon of 53% and Brunur Emmet-Teller (BET) surface area of 100 m2/g. X-ray diffraction analysis showed 91% amorphous and 9% crystallinity.
