| 摘 要： | 以铜藻为原料,在对其进行元素含量、生化组成分析的基础上,分别采用ZnCl2活化法和H3PO4活化法制备活性炭,并以活性炭得率、碘吸附值、焦糖脱色率为指标,采用正交法考察了升温速率、活化温度、浸渍比(活化剂/铜藻质量比)等因素的影响,得到最佳工艺条件.同时,采用扫描电镜(SEM)、Brunauer-Emmet-Tller(BET)比表面积等方法分析活性炭特征.结果表明,铜藻原料粒度对制得的活性炭性能影响显著,106～180μm的颗粒较为适合.ZnCl2活化法制得的活性炭吸附性能明显优于H3PO4活化法;ZnCl2活化法的最佳工艺条件为:升温速率10℃.min-1、活化温度600℃、活化时间2h、浸渍比4,在保证活性炭得率超过30%的基础上,制备的活性炭比表面积为2314.58m2.g-1,碘吸附值为835.3mg.g-1,焦糖脱色率为110%,性能明显优于其他大型海藻原料所制备的活性炭,是陆地传统活性炭原料的有效补充. |
