摘要:以竹子为原料、磷酸为活化剂,在不同条件下制备竹基活性炭,考察浸渍比、活化温度、活化时间、升温速率等因素对竹质活性炭产品吸附性能的影响,得到亚甲基蓝吸附值最高达200 mL/g、焦糖脱色率最高达120%的高吸附性能竹质活性炭。研究结果表明最佳工艺条件为:浸渍比3∶1(g∶g),活化温度400℃,升温速率10℃/m in,活化时间40 m in。对所制得的竹质活性炭产品进行扫描电镜(SEM)分析、N2吸附分析,结果表明所制得活性炭具有较高的BET比表面积(2 103 m2/g)和发达的孔结构。
Activated carbon was prepared from bamboo origin by phosphoric acid activation.The effects of different factors such as impregnation ratio,activation temperature,activation time,heating rate on adsorption properties of bamboo activated carbon were studied.The high adsorption capacity of bamboo-based activated carbon with methylene blue adsorption capacity upto 200mL/g,caramel decolorization rate upto 120% was obtained.Results showing the optimum conditions are: impregnation ratio 3∶1(g∶g),activation temperature 400℃,heating rate 10℃/min and activation time 40min.The bamboo-based activated carbons were characterized by SEM and N2 adsorption analysis,indicating that the bamboo-based activated carbon has high BET surface area(2103m2/g) and developed pore structure.
