Increasing public concerns over odors and air regulations in nonattainment zones necessitate the remediation of a wide range of odorous compounds used for industrial purpose. Currently, spraying technique using neutralizing essential oils is utilized to treat ammonia odors. The chemical analysis was performed to analyze the composition of an essential oil by GC-MS. The monoterpenes in an essential oil react with ammonia by neutralization and their reaction mechanism was elucidated. However, little information is available on the neutralization reaction with rendering air pollutants in detail. The objective of this study was to clarify the possibility of the neutralization of odors sprayed in indoor and determine the removal efficiencies in the misty aerosol by different input odor concentration. It was found that ammonia was significantly removed by the spraying technique, and the removal efficiency of ammonia was 98 %. The removal efficiencies of ammonia were also studied by the optimal conditions such as temperature and pH.
