PROBLEM TO BE SOLVED: To provide tablets for rapidly and safely preparing highly converted solutions of chlorine dioxide.SOLUTION: The tablet is a form of a porous solid containing a mixture of granule particle ingredient comprising a metal chlorite and a solid acid source, formed by compression, when added to water, producing more chlorine dioxide than when the equivalent weights of the ingredients in powder form are added to water, and giving a solution having the ratio of the concentration of chlorine dioxide to the sum of the concentrations of chlorine dioxide and chlorite anion, and greater than 0.25 by weight.COPYRIGHT: (C)2009,JPO&INPIT【課題】高変換された二酸化塩素の溶液を迅速で、安全に製造するための錠剤を提供する。【解決手段】金属亜塩素酸塩と固体酸源とを含む顆粒状の粒子成分の混合物を含んでなる多孔質固体の形状物であって、圧縮によって形成され、水に浸漬した場合、粉末の形の等量の成分を水に添加した場合よりも多量の二酸化塩素を生成し、その重量濃度が、二酸化塩素と亜塩素酸アニオンの合計に対する比で0.25を超える水溶液を与える。【選択図】なし
