PURPOSE: To provide a harmful matter removing method by which malodor is not aggravated against the harmful matter such as malodor in the atmosphere even if the intermediate product in the decomposition process of the harmful matter by a light-reactive semiconductor and desired decomposed harmful matter contain an acid and further with the efficiency in removing the harmful matter in the atmosphere improved. CONSTITUTION: A gas contg. such harmful matter as malodor is introduced into a harmful matter trapping liq. to trap the harmful matter. A liq.-permeable light-reactive harmful matter removing material contg. at least a light-reactive semiconductor, with a carrier jointly used, as required, and having various shapes including sheet is irradiated with light, the liq. having trapped the harmful matter is brought into contact with the light-reactive harmful matter removing material, and the harmful matter is decomposed by the semiconductor. |
