Study on preparation of activated carbon from cow dung by chemical activation with potassium hydroxide
Abstract: Activated carbon was prepared from cow dung using KOH as the activator in this study. Different conditions on the performance of the cow dung activated carbon samples were studied, which included the impregnation ratio, the concentration of activators, the activation time and the activation temperature. It shows that the synthesized activated carbon has the best performance under the conditions of an impregnation ratio of 1:4, a KOH mass fraction of 35%, an activation time of 60 min and the activation temperature of 700℃, under which the relative surface area can reach 979.82 m2／g, the adsorption of iodine gets up to 796.37mg / g, and the adsorption of methylene blue can be up to 10.02ml/0.1g. In addition, the appropriate conditions for Cr (Ⅵ) absorption were studied using cow dung activated carbon which was prepared under the optimum conditions.
