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 N2-BET specific surface area of activated grape-seed prepared by chemical activation were measured as about 44.09-121.33 m2/g with 100-300 wt% chemical ratio oh NaOH, KOH, ZnCl2, respectively. Removal of chromium in solution by activated carbon was carried out. |
