Abstract

It is known that a plant and microorganisms inhabiting in the rhizosphere purifies an indoor air-pollutant. The empirical model, however, involves some problems such as the long interval time needed for the measuring of purification process, and the process is modeled by simple straight line approximation. In this study, we find the purification process of the plant in detail for the basic study of a design that suitably arranges plants in a room. As an example of typical foliage plant, purification process of Epipremnum aureum for formaldehyde is measured continuously using a gas sensor. As a result, it is found that the purification rate is fixed. Therefore, the purification process could be approximated using an exponential function.
