Abstract
|
|
|
|
An activated carbon which showed big adsorption capacities of iodine, potassium permanganate and phenol was prepared from the Korean ricechaff. By scanning electron micrographs and IR spectra, it was observed that the organic components in the rice-chaff were decomposed to carbon dioxide and vapor by the pyrolysis and the activation, that activated carbon particles had carbon-carbon structures with a lot of microporosity. The adsorption capacities of iodine, potassium permanganate and phenol were determined. The adsorption isotherm of phenol was well fitted in Freundlich´s equation.
