Activated carbon was widely used in industrial application such as purification of gas and water, catalyst, or catalyst support and separation process etc., owing to its highly adsorption capacity. In this paper, activated carbon was produced from water-melon seed, which is an agricultural by-product, by chemical activation with ZnCl2, NaOH and KOH. Preparation process involve the roasting of raw material and carbonization of roasted material followed by chemical activation. N2-BET specific surface areas of activated water-melon char prepared by chemical activation were measured as 128-978 m2/g with 100-300 wt% chemical ratio of ZnCl2, NaOH and KOH, respectively. Removal of phenol in solution by activated carbon was carried out and structure change of pore surface was observed by SEM. |
