| 摘 要： | 以日常生活中废弃麻纺品为原料, KOH为活化剂, 采用炭化和活化两步法制备麻质活性炭(LAC). 采用比表面积测定仪在77 K下测定其N2吸附-脱附等温线, 通过Langmuir方程、BET方程和BJH法计算其比表面积、孔体积和孔径分布. 结果表明, 麻质活性炭的BET比表面积为1387.473 m2/g, Langmuir比表面积为1790.573 m2/g, 吸附累积总孔容达0.415 cm3/g; 采用扫描电子显微镜(SEM)、X射线衍射分析仪以及红外光谱仪对麻质活性炭的结构进行了表征, 分析其表面形貌、微观结构及表面化学官能团.

| Abstract: | In this study,activated carbon was prepared from the linen fabric waste in our daily life using KOH as activator.There were two steps,carbonization and activation in the production of linen-based activated carbon.For prepared activated carbon,a specific surface area and pore size distribution analyzer were employed to determine the N2 adsorption-desorpion at 77 K.The Langmuir equation,BET equation and BJH method were used to calculate the specific surface area,pore volume and pore size distribution.BET spec... |
