要約(日本語): We successfully developed AOS indicators that react only hydroxyl radicals (OH*), which generated under the high-humidity condition and are MB-dye pullulan thin film and MB-dye sodium alginate thin film. Here, the chemical reaction and decolorization mechanism of MB-dyed polymer thin films on exposure to AOS have been elucidated under low- and high-humidity conditions, and decolorization was observed only under high-humidity conditions. As a result, there is a weak interaction between MB-dye pullulan, MB-dyed sodium alginate was bond can be confirmed. Moreover, the decolorization of these thin ?lm indicator was caused by the MB decomposition upon exposure to OH*.
