Investigation of Air Pollution Purification Process by a Bioelectrical Potential Analysis

چکیده
ABSTRACT It is known that various plants have purification ability for indoor air pollutants. In this paper the purification mechanism of foliage plant was investigated by analyzing bioelectrical potential. It was first shown that the air purification ability of a plant depends on various environmental conditions, especially on light irradiation. It was then clarified that the bioelectrical potential responds to pollutant (formaldehyde) concentration change and also to the photosynthesis activity of the leaflet. The correlation between gas purification process and generated bioelectrical potential were discussed to make clear the gas reduction mechanism.
