An aqueous solution of a chlorite salt, an activator for rapidly adjusting the pH of the aqueous chlorite solution to generate chlorine dioxide gas and an activation inhibitor for slowly reducing the action of the activator are mixed, and chlorine dioxide gas is generated at a stable concentration from the resulting liquid composition.將亞氯酸鹽水溶液、快速地調整亞氯酸鹽水溶液的pH以產生二氧化氯氣體之活化劑、以及徐緩地降低活化劑的作用之活化抑制劑混合，並從所得到之液性組成物中以穩定的濃度產生二氧化氯氣體。
