摘要
Abstract
In order to investigate the effect of cellulose on the pore structure of activated carbon,three types of biological waste,namely waste tea,buckwheat shell,and pistachio shell,were used as raw materials for preparing activated carbon.KOH and ZnCl2 were used as activators,and the specific surface area and pore structure of activated carbon were controlled by changing the impregnation ratio.The results show that the op-timal impregnation ratio for activated carbon activated by KOH is 2.0.When KOH is used as an activator and the impregnation ratio is 2.0,the BET specific surface area and micropore volume of buckwheat shell activated carbon are the highest,reaching 904.8 m2·g-1 and 0.37 cm3·g-1,respectively,and those of pistachio shell activated carbon are 746.7 m2·g-1 and 0.31 cm3·g-1,respectively,of waste tea activated carbon are 747.8 m2·g-1 and 0.28 cm3·g-1,respectively.The results of the cellulose removal experiment show that cellulose is the main factor affecting the microporous structure of activated carbon.关键词
