Abstract

Activated carbon in this study was prepared using the two steps activation method in self generated atmosphere that comprised of carbonization and activation steps.Physical activation was used and the raw material was banana skin from Musa acuminata species. Raw materials were activated using four different sets of carbonization and activation parameters. The proximate and ultimate physical as well as chemical analyses (percentage of yield, pH value, moisture and ash content, iodine number, methylene blue adsorption capacity and morphological studies) were performed on the prepared activated carbon for the activated carbon's adsorption capacity determination. Sample B that carbonized at 200°C for 30 minutes followed by activation at 500°C for 60 minutes, obtained the highest iodine number (439.1 mgg-1) and methylene blue adsorption capacity (65.4 mgg-1) compared with other three sets. SEM morphological studies had shown that as the carbonization and activation time and temperature increased, the pores on the activated carbon increased in number and size.
