Abstract
Disclosed is a gas absorbent material having an excellent gas absorptive capacity, especially a gas absorbent material for use as an interior material for buildings, to absorb harmful gas in the room. The gas absorbent material according to the present invention comprises: a high-temperature carbonized charcoal which is carbonized at a temperature of about 800° C. or above; a low-temperature carbonized charcoal which is carbonized at a temperature of about 500° C. or below; and alginic acid or its salt or calcium oxide. A combination of a high-temperature carbonized charcoal, a low-temperature carbonized charcoal, and alginic acid or calcium oxide could have significantly improved the absorption activity of the charcoal.
