Abstract

Three activation methods, CO₂ activation, steam activation and KOH activation, were used to activate beer lees charcoal manufactured from beer lees discharged by a brewery. Liquid-phase adsorption properties of phenol, methylene blue, 1,2-dichloroethane and 1,2-dichloropropane by the resulting activated charcoal were examined.<br>The amounts of phenol and methylene blue adsorbed were found to increase in the order CO₂ activated charcoal<steam activated charcoal<KOH activated charcoal. This order coincides with the order of their pore volume of the charcoals. Phenol was adsorbed in a larger amount than methylene blue on all charcoals, probably because of its smaller molecular size. The same order of performance was found for the adsorption of 1,2-dichloroethane and 1,2-dichloropropane: CO₂ activated charcoal<steam activated charcoal<KOH activated charcoal. The amount of 1,2-dichloropropane adsorbed was twice that of 1,2-dichloroethane, even though they have similar molecular sizes. This is thought to be due to higher solubility of 1,2-dichloroethane in water, which would reflect its higher affinity for water molecules and make it more difficult to be captured by adsorbent.
