| Abstract: | The activated carbon from the stem of Eupatorium adenophorum spreng was prepared with ZnCl2 by microwave radiation.The effects of soaking time,microwave power,radiation time,ZnCl2 solution concentration on the quality of activated carbon were researched.The optimal process was as follows: microwave power was 800 W, radiation time was 12 min,ZnCl2 solution concentration was 50%.The iodine adsorption value reached 961 mg·g-1,the decolourizing capacity for methylene blue was 180 mL·g-1 and yield reached 33.8% with the optimal process.The performance reached the national standards of first-class products of ligneous activated carbon for water purification. |
