ABSTRACT:
The invention relates to a method and apparatus for generating chlorine dioxide in a reaction medium comprising a flowing gaseous carrier stream thereby providing chlorine dioxide having a low water content for use in oxidizing treatment applications which are sensitive to water. The method of the invention uses a mineral acid, such as hydrochloric acid, a hypochlorite salt, such as sodium hypochlorite salt and a chlorite salt, such as sodium chlorite salt, as reactants for generating ClO.sub.2. Air is the preferred gaseous carrier stream.
