| 摘 要： | 以玉米秸秆为原料、ZnCl2为活化剂、微波为能源制备活性炭，通过正交试验，获得制备玉米秸秆活性炭的最佳工艺条件。将产品应用于甲醛气体的去除，并与市售活性炭进行了性能比较。发现在甲醛浓度为1．94-1．97mg／m^3的条件下，试验产品的穿透时间（tB）为12min，比市售活性炭提高20％，且吸附速度更快。

| Abstract: | Technology of preparing activated carbon from corn stalks with ZnCl_2 assisted by microwave irradiation was studied.The optimum technology was obtained through orthogonal test. The product was applied to absorb formaldehyde and compared with marketed activated carbon. When concentration of formaldehyde was 1.94-1.97 mg/m~3, penetration time (t_B) of this activated carbon was 12 min which was 20 % higher than that of marketed activated carbon, and the speed of adsorption was also faster. |
