STABILIZED CHLORINE DIOXIDE AGENT AND METHOD FOR STABLY GENERATING CHLORINE DIOXIDE

PROBLEM TO BE SOLVED: To provide a stabilized chlorine dioxide agent which does not generate chlorine dioxide during preservation but stably generates chlorine dioxide in use, for the purpose of deodorization, sterilization, virus elimination, mildew-proofing and antisepsis in environmental clean-up or in transportation of food products; and a method for stably generating chlorine dioxide using the agent. SOLUTION: This stabilized chlorine dioxide agent is obtained by impregnating a porous carrier with a chlorite and an alkali agent. The porous carrier to be used exhibits alkalinity when suspended in water. The concentration of the alkali agent to be used is ≥0.1 and ≤0.7 equivalent to 1 mole of chlorite. The water content in this stabilized chlorine dioxide agent is 10 wt.% or less. This method for stably generating chlorine dioxide is as follows: when preserving the stabilized chlorine dioxide agent, the agent is shielded against carbon dioxide and water vapor; and when using the agent, the agent is brought into contact with chlorine dioxide gas and water vapor.
