The clinical evaluation was conducted in the three phases common to investigational drug studies. Chlorite must be monitored in the brewing process, especially when chlorine dioxide is used as a disinfectant on the production surfaces and equipment. Chlorate and perchlorate are oxyanions containing chlorine and oxygen atoms. Chlorine dioxide dissolved in aqueous sodium hydroxide is subsequently reduced with hydrogen peroxide to form sodium chlorite. Fundan~.
