摘　　要：以核桃壳为原料,采用微波辐照氯化锌法制备活性炭。探讨了活化条件对产品活性炭的亚甲基蓝脱色力、碘吸附值及得率的影响。最佳工艺条件为核桃壳原料10 g,微波功率580 W、活化时间7 m in、氯化锌质量分数50%。在此条件下制得的活性炭的碘吸附值为977.81 mg/g,亚甲基蓝脱色力为160 mL/g,得率为51.06%。其活化时间是传统工艺的7/90,得率是传统工艺的1.5倍左右。The activated carbon was prepared from walnut shell with ZnC12 by microwave irradiation. The effect of activation conditions on the decolorizing capacity for methylene blue, iodine value and the yield of activated carbon were investigated. The optimal technical conditions were： walnut shell was 10 g, microwave power was 580 W, activation time was 7 min, ZnCl2 solution concentration was 50 %. The decolorizing capacity for methylene blue of activated carbon was 16 mL/g, the iodine value was 977.81mg/g, and the yield was 51.06 %. The activation time was as short as 7/90 of the time for traditional technology and the yield was 1.5 times higher than that of the traditional technology.
