摘要： 以制糖业和中药厂产生的甘蔗渣、芦苇残渣、葛根残渣和甘草残渣为原料，以氯化锌为活化剂制备活性炭。在相同的活化时间下，研究了温度和浸渍率对活性炭制备的影响，并监测和分析了合适的活性炭制备条件。通过扫描电子显微镜、BET吸附测试、亚甲基蓝吸附测试、热重分析和氮吸附-脱附测试对获得的活性炭样品进行表征。实验结果表明，甘蔗渣、芦苇根残留物和葛根残留物均适合制备活性炭。对于甘蔗渣，最佳制备条件为700°C，浸渍比为1：1，此时亚甲基蓝的吸附容量达到246.83mg/g。对于芦苇残渣，最佳制备条件为600°C，浸渍比为1：2，此时亚甲基蓝的吸附量达到268.07mg/g。对于葛根残渣，最佳制备条件为700°C，浸渍比为1：2。此时亚甲基蓝的吸附容量达到297.33mg/g。

Abstract: The waste biomass produced from sugar industry and Chinese medicine factory such as bagasse, reed root residue, pueraria residue and liquorice residue were selected as the raw material for the preparation of activated carbon with zinc chloride as activator. With the same activation time, the influence of temperature and impregnation ratio on the preparation of activated carbon was investigated and the reasonable preparation conditions of activated carbon were monitored and analyzed. The obtained activated carbon samples were characterized by scanning electron microscopy, Brunauer–Emmett–Teller, methylene blue adsorption, thermogravimetric analysis and nitrogen adsorption–desorption. Analysis from the experimental data, bagasse, reed root residue, pueraria residue are suitable for preparing activated carbon. For bagasse, the optimum preparation condition was 700 °C and the impregnation ratio was 1:1, the adsorption capacity of methylene blue reached 246.83 mg/g at the moment. For reed root residue, the optimum preparation condition was 600 °C and the impregnation ratio was 1:2, the adsorption capacity of methylene blue reached 268.07 mg/g at the moment. For Pueraria residue, the optimum preparation condition was 700 °C and the impregnation ratio was 1:2. The adsorption capacity of methylene blue reached 297.33 mg/g at the moment.
Key words: Activated carbon    Waste biomass    Nitrogen adsorption–desorption    Optimize
