스킨답서스의 상토 종류 및 가스처리 횟수에 따른 포름알데히드 제거 효과

Abstract

The efficiency of formaldehyde removal by root zone was assessed. Formaldehyde removal by peatmoss was the most effective among unused growing media for planting. The rate of formaldehyde removal by peatmoss accounted for 53% of initial concentration, and those by peatmoss and perlite were 39% and 35%, respectively. When aerial plant parts of Epipremnun aureum were removed, the rate of formaldehyde removal by vermiculite was the highest (80% of initial concentration). The rates of formaldehyde removal by media removing both aerial plant parts and roots accounted for 52-54% of initial concentration. The amounts of formaldehyde removal by sterilized growing media were the smallest. The ability of formaldehyde removal by media with or without potted plants increased with frequency of exposure. Formaldehyde removal by the 15th exposure was increased approximately 7-16% compared with the 1st. Therefore, the efficiency of formaldehyde removal by potted plants placed in new house might be increased as formaldehyde emitted from materials of new building cause the increase of formaldehyde removal rate by root zone.
