Abstract

The present invention provides a chlorine dioxide generation unit that can release practically sufficient amount of chlorine dioxide for an extended period of time while being compact. The present invention provides a chlorine dioxide generation unit, characterized in that said unit comprises an agent storage space portion and at least two light source portions, said light source portion is for generating light consisting of wavelengths substantially in the visible region, said agent storage space portion stores an agent comprising solid chlorite, and said agent storage space portion comprises one or more openings so that air could move in and out of said agent storage space portion, wherein chlorine dioxide gas is generated by irradiating said light generated from said light source portion onto said agent present inside said agent storage space portion.

Dependent claims

A chlorine dioxide generation unit comprising an agent storage space portion and at least two light source portions,

wherein said at least two light source portions are for generating light consisting of wavelengths in a range of 360 nm to 830 nm,
said agent storage space portion stores an agent comprising solid chlorite, and
said agent storage space portion comprises one or more openings so that air can move in and out of said agent storage space portion,
said agent storage space portion and said at least two light source portions are arranged so that said agent present inside said agent storage space portion is irradiated by the light generated from said at least two light source portions,
wherein said agent comprises a porous substance supporting a chlorite and titanium dioxide, and the mass ratio of said chlorite to said titanium dioxide in said agent inside said agent storage space portion is 1:0.04-0.8, and
wherein said agent comprises said titanium dioxide in an amount of 0.5 wt % to 9 wt %.
