Activated carbon was produced from grape-seed, which is an agricultural by-product, by chemical activation with NaOH, KOH and ZnCl₂. It was examined the characteristics of activated carbon through BET specific surface area, N₂ adsorption isotherm, pore size distribution, average pore radius, pore volume and SEM photograph. Especially, most important factor of activated carbon produced by chemical activation was a ratio of chemical agent. The N₂BET specific surface areas of activated grape-seed char prepared by chemical activation were measured as about 44.09 -123.33 m²/g with 100-300 wt% chemical ratio of NaOH, KOH and ZnCl₂, respectively. Removal of chromium in solution by activated carbon was carried out.
