摘要:
本文以废活性炭为原料，氧化铁为添加剂，通过高温煅烧的方法制备载铁颗粒活性炭（IOCGAC）。结果表明，IOCGAC制备的最佳工艺参数为：煅烧终温为900℃，升温速率为6℃·min-1，m(氧化铁)/m（废活性炭）为4∶6，恒温时间为0.5 h，所得产品的比表面积达630.5m2·g-1，收率为50.9%。对其进行SEM，IR，XRD表征分析，结果表明活性炭的表面负载了一层致密的铁氧化物，且主要以α-Fe、Fe3O4或γ-Fe2O3的形态存在，饱和磁化强度高达66.247 emu·g-1。
Abstract:
Ironcontaining granular activated carbon (IOCGAC) was prepared with waste activated carbon and iron oxide by high temperature calcination process. The optimam parameters of the preparation process include a terminal sintering temperature of 900℃, an increasing heating rate of 6 ℃·min-1 ( starting from ambient temperature), a m/m ratio of 4∶6 (the ratio of the mass of ferric oxide to the mass of exhausted activated carbon), maintained at a thermostatic time of 0.5 h. The maximum specific surface area of the IOCGAC was 630.5m2·g-1 with a yield of 50.9%. The IOCGAC was characterized by SEM, IR and XRD. The results show that a dense layer of iron oxide is deposited on the surface of the activated carbon, which mainly exists by alpha Fe, Fe3O4或γ-Fe2O3, with a saturated magnetization strength of as high as 66.247 emu·g-1.
