Preparation and Application of Straw Activated Carbon

Abstract

The straw activated carbon produced by pyrolysis and carbonization of crop straw has not only good adsorption performance but also wide application for the treatment of sewage, air purification and soil improvement as well as the convenience of raw materials.In this paper, the preparation and present situation of straw activated carbon were described, and the factors affecting the adsorption performance of straw activated carbon were analyzed such as the type of activating agent, the concentration of activating agent, the ratio of material to liquid and the activation mode.
