Abstract
In the present study, activated carbon was prepared from
tamarind seed shells by chemical activation using
orthophosphoric acid as activating agent. The tamarind seed
shells were impregnated with orthophosphoric acid in suitable
ratio. This impregnated mass was carbonized in a modified
muffle furnace at 500-9500 C. Various process parameters
such as ratio of impregnation, temperature of carbonization,
time period of carbonization were optimized. The prepared
activated carbon was characterized for proximate & ultimate
analysis, iodine number, N2-BET surface area, pore volume,
scanning electron microscopy (SEM) and FT-IR
spectroscopy. It has been observed from the results that the
produced activated carbon has very high iodine number: 2010
mg/g, N2-BET surface area: 2447 m2/g and pore volume:
1.4003cm3/g. The SEM of activated carbon shows lot of
cracks, crevices and different size pores. FT-IR spectra show
the presence of various functional groups with predominant presence of phenolic -OH. Phenol adsorption and kinetic
studies were carried out to evaluate the adsorption capacity of
produced activated carbon in comparison with commercially
available Filtrasorb 400(F-400) activated carbon. It has been observed that the produced activated carbon has better adsorption capacity than commercially available F-400 activated carbon.
