在无N2条件下，以农业废弃物花生壳为材料，分别以氯化锌和碳酸钾为活化剂制备活性炭。通过正交试验以亚甲级蓝的吸附为考察对象，获得最优工艺条件。通过扫描电镜观测活性炭表面形貌并研究各因素吸附效果的影响，与市售活性碳对比。氯化锌活性炭最优工艺条件：浸渍温度90℃、浸渍时间12 h、物料比1∶2、活化温度650℃、活化时间60 min。碳酸钾活性炭最优工艺条件：浸渍温度120℃、浸渍时间6 h、物料比1∶2、活化温度650℃、活化时间100 min。扫描电镜观测结果表明，活性炭表面均形成了丰富的1μm左右的孔状结构，并且以ZnCl2为活化剂的活性炭形成部分超大孔径，造成表面有少量的坍塌结构。自制的两种最优活性炭的吸附量均大于商业活性炭，同时自制活性炭吸附平衡时间更短，可以使用的温度范围更宽。

In this study,attempts were made to prepare activated carbon from peanut shell by activation of ZnCl2 or K2 CO3 without N2. We use methylene to investigate its adsorption ability,and Scanning Electron Microscope(SEM)to observe the surface topogra-phy of the actibated carbon. The results of this paper are follows:ZnCI2 activated carbon:assembly time 12 h,soakage temperature of 90℃,the material ratio of 1∶2,activation time 60 min,the activation temperature of 650℃. K2 CO3 activated carbon:assembly time 6 h,soakage temperature of 120℃,the material ratio of 1∶2,activation time 100 min,the activation temperature of 650℃. The SEM results show that some pore can be observed in the surface of activated carbon. The adsorption ability of peanut shells activated car-bon is better than the commercial activated carbon significantly.
