| Research Abstract |
A newly developed mini-scale testing system for obtaining the gaseous chemical removal performance of interior finishing materials is proposed in this report. The system was designed to perform dynamic analysis and it consists of a small gas flow channel device, where the test material is placed, and an analysis element, for detecting gaseous pollutants. Six interior wall materials and "limonite", which is an natural soil mined in Mt.Aso, were set in the channel device. Hydrogen sulfide or formaldehyde gas was introduced, passed through the surface of the material inside the cavity of the middle plate, and the concentration at the outlet of the channel was measured by the fluorescence monitor. The results indicated that the seven materials could be classified into 3 types according to the removal mechanism: ineffective, physical and chemical adsorption. The relationship between removal efficiency and flow rate can be obtained easily by this small testing device and simple method.
