[Method] Using potassium hydroxide as activator and glutinous rice straw as raw material, activated carbon was prepared. [Result] The optimum technological 究 conditions for preparation of activated carbon from glutinous rice straw were as fol- lows: activator concentration of 2 mol/L, activation time of 60 min, activation tem- 梁健，蔡勤，李波，吴昌演，刘汉林，程静，周健 perature of 600 ℃ and carbonization temperature of 450 ℃ . The adsorption values 齐，柏松 * （贵州理工学院化学工程学院，贵 of methylene blue and iodine by activated carbon prepared from glutinous rice straw 州贵阳550003 ） were 10.21 ml/0.1 g and 920.74 mg/g respectively under the optimal conditions. The 摘 要 目的 提高糯稻秸秆的综合利用价 quality of the prepared activated carbon met the grade two of water quality purifica- [ ] tion-using activated carbon quality standard. [Conclusion] This study will provide cer- 值， 并为活性炭的制备提供新的原材料。 [方 tain references for comprehensive utilization of glutinous rice straw and preparation 法] 以氢氧化钾为活化剂，糯稻秸秆为原料制 of high-performance activated carbon.
