Study on the Preparation and Adsorption Properties of Activated Carbon Obtained from Chinese Herbal Medicine Residue

Abstract:

In this paper, we use residue of ten different Chinese herbal medicine as raw material and ZnCl2, KOH,K2CO3 as activator, using chemical activation method to prepare activated carbon, and we do performance testing on the activated carbon. The experimental process includes the preparation and properties testing of activated carbon, as well as testing the content of leading components of lignin in these Chinese herbal medicine raw materials and their calorific values. We've studied the relationship between leading components of these raw materials and out put and properties of the activated carbon. As a result, we got that using KOH and K2CO3 as activator to prepare activated carbon is a good choose for residue of Chinese herbal medicine belonging to rootstock which contains high content of lignin.And ZnCl2 for residue of Chinese herbal medicine belonging to cane.
