抄録

<p>It has become clear that 1,4-dioxane exists not only as a contaminant in aquariums, but also in the atmosphere at a constant concentration. It has been reported that 1,4-dioxane is produced from the highly reactive lime in bag filters from industrial waste incineration treatment facilities; however, the source of the 1,4-dioxane that is released to the atmosphere is primarily surfactant manufacturing plants. In this study, in order to clarify the mechanism of 1,4-dioxane formation in a bag filter coated with highly reactive lime, and to accurately evaluate the amount of 1,4-dioxane produced from a certain amount of this highly reactive lime, headspace-GC/MS was explored as an analytical method. The formation of 1,4-dioxane in the bag filter was successfully reproduced. In addition, the amount of 1,4-dioxane produced for 2.0–40 μg g−1 of lime was found. Also, Headspace-GC/MS was found to be the only evaluation method that could be used to study highly reactive lime without generating 1,4-dioxane. Further, it is an excellent method for confirmation when selecting highly reactive lime for use in industrial-waste incineration treatment facilities.</p>
