| 摘 要： | 研究了以自制的快速裂解产物竹炭为原料,采用KOH-微波辐射活化法制备竹质活性炭.利用正交试验探讨了不同因素对竹质活性炭性质的影响.最佳工艺条件为KOH质量分数 25 %,浸渍时间 24 h,微波功率 800 W,活化时间 7 min,所制备的活性炭产品的碘吸附值为 1 239.08 mg/g,亚甲基蓝吸附值为 274.95 mg/g,比表面积为 1 394.16 m2/g,亚甲基蓝吸附值为国家一级品标准(GB/T 13803.2-1999)的2.04倍,同时测定了活化前后竹炭的红外光谱.结果表明,活化后竹炭表面结构有了较大的修饰,增加了较多的表面化学官能团,从而提高了竹炭的比表面积和吸附性能.

| Abstract: | The preparation of activated carbon from bamboo charcoal by fast pyrolysis using KOH-microwave irradiation method was researched.The effects of different conditions on the properties of bamboo-based activated carbon were systematically studied via orthogonal experiments.The optimum conditions were as follows: mass fraction of KOH solution 25 %,impregnating time 24 h,microwave power 800 W and activating time 7 min.Under the above conditions,iodine adsorption value of activated carbon was 1 239.08 mg/g,methyl... |
