Abstract
The present invention relates to methods and devices for the production of controlled quantities of chlorine dioxide at concentrations which are effective to function as a deodorant or a germicide. Aqueous chlorite compositions such as aqueous sodium chlorite are brought into contact at a controlled rate through capillary means, e.g. a wick with an absorbent pad containing acid or other reactant which will react with the chlorite and form chlorine dioxide.
