Abstract:
The preparation of activated carbon from camellia nutshell was introduced, using potassium hydroxide as the catalyst. The influences of activator concentration, ratio of solid to liquid, activation temperature and activation time on iodine sorption value and methylene blue decolorization rate of activated carbon were studied. The orthogonal results showed that the best preparation conditions were as follows: activation temperature 700℃, the ratio of solid to liquid 1:5, the concentration of catalyst 6mol/L and activating time 90 minutes. Then the decolorization rate and the iodine sorption value got up to 96.25% and 1145.59 mg/g，respectively, which conformed to the standards of commercial activated carbon.
