氯化锌法制备竹活性炭

Preparation of Activated Carbon from Bamboos by Zinc Chloride

活性炭的制备主要以木材和煤作为原料,采用化学法和物理法进行活化.本文在活性炭原料的选取中,采用竹子来代替木材和煤炭,使用氯化锌法制备活性炭,对制备工艺进行了研究,得到的最佳工艺条件为:活化温度600℃,浸渍比150%,活化时间为60～90min.

Activated carbons are mainly prepared from wood and coal by chemical or physical activation.Now instead of wood and coach,we are trying to use the bamboo saw to prepare the high capable activated carbon by zinc chloride.We have got the best sample of activated carbon under the conditions:impreynation ratio of 150%;activation temperature of 600℃ and activation time of 60 min.The performance of the activated carbon istested by iodine and methylene blue adsorption.
