Abstract

Activated carbon powders (ACPs) with unique morphologies were prepared from wool fibers by chemical activation at different carbonization temperatures and impregnation ratios. These materials were characterized by elemental analysis, scanning electron microscopy (SEM), thermogravimetric analysis (TGA), adsorption/desorption of N ₂ and methylene blue (MB) adsorption. The surface properties of the activated carbon powders (ACPs) were significantly influenced by the activation temperature and activation process. ACPs activated by 2-step K ₂CO ₃ (K ₂CO ₃/char value of 2) at 600°C had a high surface area (438m ²g ^-1), and a large pore volume (0.197cm ²g ^-1) with an average pore diameter of 0.858nm. They were also very efficient in the adsorption of MB.
