To provide a method for generating chlorine dioxide gas, by which chlorine dioxide gas capable of being utilized for deodorization, sterilization, mildewproofing and corrosion proofing at the time of environment purification, transportation of foods, or the like can be sustainedly generated for a long period of time.
The method for generating chlorine dioxide gas comprises sustainedly generating the chlorine dioxide gas from a gel-like composition obtained by adding an activating agent, a water absorbing agent and a water-retaining agent to an aqueous chlorite solution and converting the resulting mixture into a gel. At this time, a gas-generation regulator may be further added to the aqueous chlorite solution. The method for generating the chlorine dioxide gas comprises sustainedly generating the chlorine dioxide gas from a gel-like composition obtained by preparing solid chlorite, the activating agent, the water absorbing agent and the water-retaining agent as solid materials and converting the solid materials into a gel by the addition of water to the solid materials when chlorine dioxide gas is used. At this time, the gas-generation regulator may be further prepared as one of the solid materials.
