PROBLEM TO BE SOLVED : To solve the problem wherein dilution of an aqueous chlorine dioxide solution (ClO2) or a stabilized chlorine dioxide solution (NaClO2), which are strongly alkaline (pH : around 10), with water (neutral, pH; 7) results in emission of a strong chlorine odor because acidification occurs according to difference in concentration (the shift of pH is observed), and the problem wherein strongly alkaline natural water (pH : around 10) is extremely rare, only regarded as hot spring water or mineral water with excellent characteristics, and is thus not exploited for any new application. SOLUTION : The method for diluting the aqueous chlorine dioxide solution or the stabilized chlorine dioxide solution with strongly alkaline natural water comprises diluting the aqueous chlorine dioxide solution or the stabilized chlorine dioxide solution of prescribed concentration (ppm), which has a strongly alkaline pH of around 10, with strongly alkaline natural water with a strongly alkaline pH of around 10, thereby completely or substantially eliminating shift of pH so as to completely or substantially prevent emission of the chlorine odor due to acidification associated with the shift of pH. The aqueous chlorine dioxide solution or the stabilized chlorine dioxide solution diluted thereby is also provided. COPYRIGHT : (C)2011, JPO&INPIT
