A Preliminary Study on the Preparation of Activated Carbon from Cyrtosperma chamissonis Petioles via Single Step H3PO4 Activation

Article Preview

Abstract:

In this study, highly porous activated carbon was prepared from Cyrtosperma chamissonis petioles via single step H3PO4 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 Na2S2O3 volumetric method, SEM/EDX and N2 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 m2g-1 respectively with yield percentage of 35.82. This preliminary study proves the successful conversion of plant waste into value added porous materials.
