PREPARATION OF BEER LEES-DERIVED ACTIVATED CARBON AND ITS APPLICATION IN REMOVING PURINE COMPOUNDS

摘要

The application of activated carbon prepared from beer lees in the removal of purine compounds in beer was investigated. In this study, activated carbon was prepared from beer lees using zinc chloride and carbon dioxide as activation agents. The effect of the physical properties of activated carbon derived from beer lees on its adsorption of purine compounds was studied. Various activated carbons prepared using the abovementioned activation agents were used to remove purine compounds in beer. We determined that the size of the purine compounds and the pore structure of the activated carbon may have an effect on its adsorption of purine compounds. The beer lees-derived activated carbon can adsorb the purine compounds in beer nearly as effectively as commercial-grade activated carbon made expressly for this purpose.
