A Preliminary Study on the Preparation of Activated Carbon from <i>Cyrtosperma</i> c<i>hamissonis</i> Petioles via Single Step H<sub>3</sub>PO<sub>4</sub> Activation
In this study, highly porous activated carbon was prepared from Cyrtosperma chamissonis petioles via single step H 3 PO 4 activation. The effect of impregnation temperature (RT – 90 °C) on the yield, porosity and surface area was investigated. The synthesized activated carbons were characterized by Na 2 S 2 O 3 volumetric method, SEM/EDX and N 2 adsorption-desorption analyses. The optimization investigation clearly showed that the impregnation temperature affected on the yield and the specific surface area of the materials. Under the optimum impregnation temperature of 75 °C, the registered iodine number and BET surface area were 1129.23 mgg -1 and 1390.41 m 2 g -1 respectively with yield percentage of 35.82. This preliminary study proves the successful conversion of plant waste into value added porous materials.
