| 摘 要： | 研究利用机械力化学技术制备了性能良好的活性炭。采用Central Composite Design中心复合设计和响应面分析,对影响活性炭碘吸附值的主要影响因素进行多项回归模型建立和参数优化,并通过低温液氮(N2/77 K)吸附测定较优条件下制备的活性炭的比表面积、孔容及孔径分布。结果表明,利用氯化锌为活化剂的机械力化学技术制备活性炭的较优工艺条件为:氯化锌与绝干木屑的质量之比(锌屑比)值3.00,研磨时间10 min,活化温度584℃,活化时间2.5 h,此条件下制备的活性炭碘吸附值为1 262.47 mg/g。

| Abstract: | The regression model for factors affecting iodine adsorption of the prepared activated carbon was established and optimized by using Central Composite Design′s central combination design and response surface method.The test of single factor showed the activated carbon with good adsorption properties prepared by mechanochemical process.The pore volume and pore size distribution of the prepared activated carbon under the optimum condition were derived from adsorption isotherms(N2 at 77 K).The results showed that the optimum technology condition include ZnCl2/wood flour ratio 3.00,milling time 10min,activation temperature 584 ℃,activation time 2.5 h. |
