Abstract
The removal of acetaldehyde, which is one of main components of food waste odor was investigated using biomass char as a nanoporous carbon absorbent. The biomass char adsorbent obtained from the pyrolysis of Geodae-Uksae was modified by the water and KOH treatment. The modified char absorbent had a higher acetaldehyde removal efficiency than nanoporous CMK-8 possibly due to its high oxygen and nitrogen functional groups.
