【Increasing public concerns over odors and air regulations necessitates the remediation of a wide range of odor substances for industrial and indoor purpose. Currently, the wet scrubbing technique by neutralization using oils is being used to treat odor substances such as Ammonia( $NH_3$ ), Methyl Mercaptan( $CH_3SH$ ), Hydrogen Sulfide( $H_2S$ ), Methylamine( $CH_3NH_2$ ), Acetaldehyde( $CH_3CHO$ ). The chemical analysis is performed to analyze the composition of an Arctium Lappa Root extract by VOC analyzer(Phocheck 5000Ex, ION SCIENCE co.) The objectives of the this study are to clarify the possibility of the neutralization of odors sprayed in the fixed bed and determine the removal efficiencies for different input odor concentrations. It is found that Ammonia( $NH_3$ ), Methyl Mercaptan( $CH_3SH$ ), Hydrogen Sulfide( $H_2S$ ), Methylamine( $CH_3NH_2$ ), Acetaldehyde( $CH_3CHO$ ) are significantly removed and their removal efficiencies are higher than 98%. The kitchen detergent with Arctium Lappa Root extract showed excellent removal efficiencies of odor substances and high possibility for the development of kitchen detergent with odor removal.】
