| Abstract: | The activated carbon was prepared from rice straw by activation of sodium hydroxide. The optimum conditions were obtained by using the orthogonal experiment method. The results showed that the best sample of activated carbon was obtained under the conditions of the ratio of NaOH/coal of 2, activation time of 60 min, activation temperature of 600 ℃ and the carbonization temperature of 350 ℃. The methylene blue adsorption value and iodine adsorption value of the prepared activated carbon were 29.2 mL/0. 1 g and 1 706.98 mg/g, respectively. The product quality index was close to the activated carbon standard for water ourification. |
