Abstract
According to the present invention, provided are a method whereby a sterilization/deodorization gas is supplied by irradiating a stabilized chlorine dioxide gel or liquid with ultraviolet radiation, and a sterilization/deodorization gas supply apparatus which comprises: a chemical container used to hold a chemical gel or liquid which is used for sterilization and deodorization, and as an insecticide or an insectifuge; an ultraviolet radiation unit for projecting ultraviolet radiation onto the chemical and for generating a dispersed gas; and a gas discharge unit for extracting from the chemical container gas elements that are to be dispersed by the ultraviolet radiation unit. With this arrangement, a chlorine dioxide gas that can effectively perform sterilization and deodorization can be easily and safely stored, handled and supplemented by employing the chemical reactive propagative effects of ultraviolet radiation.
