Availability of the unburned carbon separated from anthracite and bituminous coal ash as an activated carbon was evaluated by adsorptivity of iodine and methylene blue depending on activation. The unburned carbon was washed by 3N-HCl and chemically activated with sodium hydroxide. Unburned carbons had already adsorption ability for iodine and methylene blue up to 40-60% of powder-type(≤100mesh) commercial activated carbon. Their adsorptivities could be level up to ≥80% of commercial activated carbon through chemical activation with sodium hydroxide at 600～ 700℃ for 1 hour. All results obtained suggest the possibility that unburned carbons can be successfully reused to a substitution of activated carbon through a proper chemical activation without any limitation of coal-type.
