摘　　要：使用榛子壳为碳源,本研究是使用两个不同的活化剂联合使用制备榛子壳活性炭。使用BET表征其孔隙结构,使用扫描电镜表征其外貌,使用能谱表征元素含量。结果表明:使用硝酸锌和氢氧化钾联合活化剂生产的榛子壳活性炭具有较高的比表面积和介孔孔径;使用硝酸锌和氢氧化钾联合活化剂生产的榛子壳活性炭比表面积随温度的上升比表面积增加;最高表面积可达2 380 m2/g。Using hazelnut shell as the carbon source, hazelnut shell activated carbon was prepared by using two different activators.The pore structure was characterized by BET, its appearance was characterized by scanning electron microscopy, and the elemental content was characterized by the energy spectrum. The results showed that the hazelnut shell activated carbon produced by using zinc nitrate and potassium hydroxide as activator had higher specific surface area and mesoporous pore diameter. The specific surface area of hazelnut shell activated carbon increased with the increase of activation temperature. The maximum surface area was up to 2 380 m^2/g.
