As early as 1811, U.S. scientists H. Davey, and hydrochloric acid aqueous solution using KClO3 the first time a collection of synthesized and chlorine dioxide gas. However, until this century, 30 years, ClO2 was able to safely and economically in mass production, began the extensive application of industrialization. In 1944, the first chlorine dioxide treatment as a disinfectant for Niagara Falls, New York City drinking water. The late seventies of last century, developed since the stabilizer of chlorine dioxide, chlorine dioxide as a bleaching agent and disinfectant, has been widely used in pulp bleaching, food processing, disinfection and sterilization areas and other areas of water purification, and fully has shown its strong bleaching and disinfection capabilities.
