INK COMPOSITION FOR DETECTING DISSOLVED OZONE AND METHOD OF DETECTING DISSOLVED OZONE

摘要

An ink composition and method by which dissolved ozone which can be contained in a liquid to be examined can be more easily detected/determined with higher certainty. The method, which is for detecting dissolved ozone contained in a liquid to be examined, comprises (1) a step in which an ink composition for dissolved-ozone detection comprising at least one water-soluble dye selected among anthraquinone dyes, azo dyes, methine dyes, oxazine dyes, triarylmethane dyes, and xanthene dyes and water is dropped into the liquid to be examined and (2) a step in which the ink composition dropped is examined for a color change.
