A method of producing chlorine dioxide involves generating chlorine dioxide gas by deforming a container body of a chlorine dioxide generator which is deformable in response to application of a force to the container body from outside of the container body. The deforming of the container body causes an enclosure contained in the cylinder body to be broken to bring an aqueous chlorite solution into contact with a solid acidic composition to generate chlorine dioxide gas that is discharged via a gas discharge port of the container body to outside of the container body. The method additionally involves submerging in water at least the gas discharge port of the container body during the generation of the chlorine dioxide gas to dissolve the chlorine dioxide gas discharged via the gas discharge port in the water.

Chlorine dioxide generator

A chlorine dioxide generator includes a container body deformable in response to application of a force from the outside. The container body contains therein a solid acidic composition and an aqueous chlorite solution under a non-contact state from each other. The solid acidic composition comprises a porous material containing an acidic substance. The aqueous chlorite solution is sealed within an easily breakable enclosure. In operation, when the container body is deformed, the enclosure contained therein is broken to bring the aqueous chlorite solution into contact with the solid acidic composition, whereby chlorine dioxide gas is generated. This generated chlorine dioxide gas is discharged via a gas discharge port to the outside of the container body.
