Abstract

It is known that the porosity and adsorption capacity in a carbon that depended on the nature of precursors, pyrolysis and activation conditions, and the ash content. Porous carbons have been prepared from banana fruit (Musa Accuminata) in different temperature and time limits. The banana fruit has gone through carbonization before activation process occurs. Yield percentages shows that they were not many differences as moisture and ash gave higher percentages as temperature and time activation increase. Iodine number gives a low adsorption value, which is different in time and temperature in comparison. Methylene blue adsorption value shows the same configuration as iodine number. The SEM micrographs taken, proved the porosity of samples, which shows majority of mesopores and macropores volume. All the analyses have been compared with the Pharmaceutical activated carbon standards for medical grade activated carbon.
