| 摘 要： | 采用正交试验方法研究影响混合碱法制备甘蔗渣基活性炭性能的4种工艺因素：活化剂配比、料液比、活化温度及活化时间。结果表明，影响甘蔗渣活性炭吸附性能的工艺因素的强弱秩序为：活化时间、活化温度、活化剂配比、料液比；样品的亚甲基蓝吸附值随着活化温度的升高或活化时间的延长而呈先增后降的变化规律。其最佳工艺为：活化剂配比（KOH：NaOH）7．4：1、料液比1．18：1、浸渍时间24h、活化温度923K、活化时间0．42h。经优化工艺制得的甘蔗渣基活性炭样品的亚甲基蓝吸附值为12．7ml／0．1g，为活性炭国家标准（GB／T13803．4—1999）中一级品的1．4倍。

| Abstract: | The influencing factors such as the ratio of activating agents,the ratio of bagasse to mixed base,the activation temperature and time on properties of bagasse-based activated carbon prepared by mixed base method were systematically investigated by means of orthogonal test.The results showed that the sequence in terms of influence degree on the adsorption performance of the samples was as follows:activation time>activation temperature>activating agent>the ratio of bagasse to mixed base.The methylene blue ads... |
