<p><P>PROBLEM TO BE SOLVED: To provide an ozone detection sheet that easily detects the accumulated amount of ozone in gas as a measuring object by an accumulation effect in an easily portable state without using electric power, and can be easily portable by an individual. <P>SOLUTION: A detection solution 101 that has about 20 wt.% of humectant and is an aqueous solution made alkaline by dissolving a coloring matter made of alizarin and humectant made of glycerol and dissolving base (alkaline substance) is prepared. A sheet-like carrier 103 made of cellulose filter paper is dipped in it for 30 seconds, and the detection solution 101 is impregnated, and an impregnation sheet 104 in which the detection solution 101 is impregnated is formed. Then, the impregnation sheet 104 is pulled up from the detection solution 101, and dried in drying nitrogen to evaporate and dry solvents such as moisture impregnated in the impregnation sheet 104, and an ozone detection sheet 105 is formed. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
