摘要
以桉木屑为原料,氯化铁为活化剂,微波加热的方法制备生物质多孔炭,研究了制备工艺条件对多孔炭的得率,吸附性能和铁含量的影响。结果表明,桉木基多孔炭的较优制备条件为:氯化铁与桉木屑的质量比为1∶1,微波功率为750 W,微波辐照时间为25 min。在该条件下,桉木基多孔炭的得率为45. 5%,桉木基多孔炭的亚甲基蓝吸附值、碘吸附值和苯酚吸附值分别为133. 3,492. 4,229. 3 mg/g,铁含量为0. 10%。
Eucalyptus sawdust was utilized to produce porous carbon by microwave-assisted heating and activation with FeCl3. The effect of the preparation process conditions on the yield of porous carbon,adsorption capability and iron content were investigated. The result showed that the optimum process conditions were obtained as follows: the mass ratio of FeCl_3 to Eucalyptus sawdust was 1,microwave power and microwave heating time were 750 W and 25 min; under the above optimum preparation conditions,the yield of the prepared porous carbon was 45. 5%,the adsorption capacity of methylene blue,iodine and phenol of the porous carbon were 133. 3 mg/g,492. 4 mg/g and 229. 3 mg/g,and iron content of the prepared porous carbon was 0. 10%.
