<p><P>PROBLEM TO BE SOLVED: To provide an ozone gas filter capable of visually determining the presence or absence of ozone removing capacity. <P>SOLUTION: A prepared fibrous carrier 103 is dipped in an ozone gas decomposition chemical solution 101 formed by adding pure water to 4.5g of indigo carmine, 350g of citric acid and 1,250g of glycerol to be 5.0 litters in total; after 10 minute-dipping, for example, the ozone gas decomposition chemical solution 101 is impregnated into the fibrous carrier 103 to form an impregnated carrier 104 impregnated with the ozone gas decomposition chemical solution 101. The impregnated carrier 104 is dried to form a carrier sheet 105 carrying an ozone gas decomposition component. The carrier sheet is wound into a cylindrical column, and the side face thereof is covered with a transparent resin sheet 107 to form an ozone gas filter 108. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
