| 摘 要： | 为了探讨以丝瓜络为原料制备高比表面积活性炭的最佳条件，通过设计正交实验，研究了碱炭比、活化温度、活化时间和升温速率等因素对KOH活化丝瓜络制备活性炭性能的影响。结果表明：KOH活化丝瓜络制备活性炭的最佳条件为：碱炭比为4、活化温度800 ℃，活化时间30 min，升温速率10 ℃/ min。在此条件下制备的活性炭为多孔、非晶型的无定形碳，具有高的比表面积（3545 m2/g）和强的吸附性能，其碘值和亚甲基蓝值分别达到2926 mg/g和528.58 mg/g；为丝瓜络的高值化利用提供了一条有价值的途径。

| Abstract: | In this study,activated carbon with high surface area was prepared from Luffa cylindrical sponge by KOH activation.The effects of KOH/C ratio,activation temperature,activation time and heating rate on the properties of as-prepared activated carbons were investigated by means of orthogonal test design.Results showed that the optimal condition is following:KOH/C weight ratio 4, activation temperature 800 ℃,activation time 30 min,and heating rate 10 ℃/min.The as-prepared activated carbon is porous and amorphous,which has high surface area of 3545 m2/g,and the iodine and methylene blue adsorption value reached to 2926 mg/g and 528.58 mg/g,respectively.This study presents a valuable pathway for comprehensive utilization of Luffa cylindrical sponge. |
