Abstract: Activated carbon with high quality was prepared from a forest waste of bamboo dust using potassium hydroxide as an activating agent. Effects of activation temperature, activation time, and impregnation time on adsorption of activated carbon were studied by orthogonal test. The optimum parameters for preparation of activated carbon were: 1:4 of the ratio of bamboo dust to potassium hydroxide solution, 1 h of impregnation time, 900℃ of activation temperature, and 90 min of activation time. The prepared activated carbon under the condition of optimum parameters had the structure of enormous micropore and its surface area was up to 2415 m2/g.

Key words: activated carbon, bamboo dust, orthogonal test, potassium hydroxide
