Abstract
Activated carbon from papyrus plant was prepared by the chemical activation with sulfuric acid 3:1 (wt./wt.). The prepared activated carbon then burningat 600°C under N2 atmosphere for 2 h. The produce coded AC0, further modification of AC0 by using different oxidizing and reducing solutions. The solutions were a (mixture NaNO3 with KMnO4 in 10% H2SO4 coded (AC1) 10% ZnCl2 coded (AC2) 10% NaBH4 coded (AC3) 10% HNO3 coded (AC4). Characterization propertiesforthe prepared activated carbons (AC0-AC4) were accomplished using techniques including FTIR, SEM, XRD, TGA and BET. BET showed a substantial increase in the surface area of AC2, AC3, accompanied by reduced intensities of certain IR vibrations (1720, 3420 cm-1) as well as absence of pronounced peak at 2θ = 25 in XRD. While samples prepared by the treatment with oxidizing reagent showed a noticeable increase in the intensity of IR band at 3420 cm-1 as well as emergence of vibration band at 1720 cm-1. Moreover, the peak at 2θ = 25 were showed an increase in the intensity. The pore volume showed variable behavior depending on the type of the reagent used for the treatment. However, the pore volume increased by the treatment with NaBH4 and decreased by the treatment with NaNO3/KMnO4 solution. The TGA thermographs were with a good accordance with pore volume indicating a high carbon percentage more than 82% by the end of heating cycle and departure of volatile hydrocarbons as a result of treatment with reducing agents particularly NaBH4 right from the beginnings.
