| description | In this work, wood bark was liquefied to prepare activated carbon fibers, which were obtained through melt-spinning, stabilization, carbonizing, and stream activation. The effects of varying activation temperature on the pore structure and the adsorption capacity of the liquefied wood bark activated carbon fibers (LWBACFs) were studied using analysis of nitrogen adsorption-desorption isotherms and static adsorption of copper (II) ions from aqueous solution. The results indicated that higher specific surface area was obtained as the activation temperature increased. The specific surface area reached a maximum of 1962 m2/g with an average pore diameter of approximately 2 nm. Carbonization at 200 °C played an important role in the formation of pore structure. The adsorption of copper by LWBACFs was high, with a peak of 15 mg/g. All parameters showed that LWBACFs performed well in the adsorption of micropores. |
