| Abstract: | Activated carbon was prepared from straw black liquor lignin using phosphoric acid as activation agent.The function of phosphoric acid in activation process was discussed,and effects of reaction conditions such as ratio of activation reagent to material,the temperature and the activation time were investigated.The results showed that the lignin of straw black liquor was a good material for preparing activated carbon.Phosphoric acid acts as both the dehydrating agent and the protective agent during the activ... |
