摘要
利用Milestone 2 0 0氮气吸附仪及X ray分析仪对淀粉质活性炭经高温处理后孔隙结构的变化做了评价。结果表明 :高温处理使活性炭中孔塌缩 ,中孔容积减小 ,微孔容积略有变化 ,堆积比重增大 。
The pore structure changes of activated carbon from starch treated with high temperature were inspected by the apparatus of N 2 adsorption and X ray analysis. The results showed that high temperature treatment of activated carbon resulted in subsided mesopore, decreased mesopore volume, basically unvaried micropore volume, increased apparent density and enlarged microcrystalline.
