The purpose of this study was carried out to estimate removal possibility of IBMP and IPMP causing odor in raw water. As a result of Freundlich isotherm. IBMP was superior to IPMP in adsorptive capacity. Adsorptive capacities of activated carbon were found to be in order of Lignite, Coconut shell, and Charcoal. These were well fitted with Freundlich isotherm. According to adsorption breakthrough tests for Lignite GAC, breakthrough time of IPMP and IBMP were 5.7hr and 5.5hr, respectively. Because adsorptive capacities of target material were very different with pore size distribution, it seemed that Lignite and Coconut shell based activated carbons were recommended in order to remove door compounds.
