Indoor chemicals emitted from building materials has been caused a sick building syndrome and environmental disease like an atopic dermatitis. A development of absorptive building materials has been applied to remove indoor contaminants and to improve indoor air quality. In this study, ash as natural porous mineral materials that are used as raw materials for Sorptive building materials to improve the performance of the adsorption of Toluene. The copper oxide was impregnated into the porous surface of volcanic ash to give the removal performance of Toluene by oxidation. The mass impregnated Cu(No₂)₃(Copper nitrate) was set 1.0~2.0 wt% compared to The amount of ash. After impregnating the surface area and X-ray diffraction graphs were measured. When after 30 minutes of natural ash removal efficiency of 77.82% showed and removal rates gradually decrease with the passage of time when the 420 minutes has elapsed the removal efficiency was as low as 5.19%. Copper oxide was impregnated with 2 wt% when a 30-minute period, the removal efficiency was 95.19% and when the 390 minutes after removal efficiency of 92.93% was retained. Results of this study, the copper oxide impregnated ash removal efficiency of toluene was higher than the natural state of ash. By applying a modified natural material that will be possible to develop high-performance functional building materials than conventional things.
