Abstract: By chemical method coke powder activated carbons was prepared using coke powder as raw material and KOH as activator.The coke powder activated carbon with the optimum specific surface area as 185m2/g was obtained through orthogonal experiment with three factors and four levels.The influence degree of three factors on the adsorption of activated carbon powder was: activation temperature> alkali carbon ratio(KOH and coke mass ratio)>activation time.The samples before and after activation were comparatively de...
