ABSTRACT:
A vacuum operated electrolytic generator can be used to produce a chlorine dioxide solution or a mist of chlorine dioxide from a buffered aqueous alkali metal chlorite solution in one pass through an electrolytic cell. The cell contains a high surface area anode, a corrosion-resistant highly conductive cathode, and a cation ion exchange membrane between the anode and cathode. An eductor is used on the anolyte effluent line to create a vacuum and draw the anolyte through the cell. Either motive water or a motive inert gas (such as air) is used in the eductor. Preferably, an eductor is used in the catholyte effluent line. An ascending anolyte effluent line with a non-corrosive check valve leads from the cell to the anode eductor. Sensors are used to monitor the composition of the anolyte effluent and/or the anolyte feed. The final product is a chlorine dioxide solution when water is used for the eduction. The final product is a mist consisting essentially of gaseous chlorine dioxide, an inert gas, and water vapor when an inert gas is used for the eduction. The mist is useful for application crop, soils, produce such as vegetables, fruit, and tobacco, fields, storage cellars, and the like.
