	Method of producing chlorine dioxide using sodium chlorite and a water-retaining substance impregnated in zeolite or in ...
		In some embodiments, the invention is a method for producing chlorine dioxide by activating zeolite crystals (previously impregnated with sodium chlorite and calcium chloride) with excess protons or activating an aqueous solution of sodium chlorite and calcium chloride with excess protons.
		Another such embodiment is an aqueous solution of sodium chlorite and at least one chemical selected from the group consisting of magnesium sulfate, potassium chloride, potassium hydroxide, and calcium chloride, preferably comprising 1%-6% of sodium chlotite, 0.5%-2% of said at least one chemical, and 92%-98.5% of water (by weight).
		Each of sodium metabisulfite and sodium bisulfite is considered an "oxidizer" in the sense that the latter expression is used herein, since each reacts (in the presence of the absorbed water) to release sulfur dioxide which in turn reacts with one or more of the other impregnating substances to produce chlorine dioxide.

		Therefore, as freezing proceeds, the chlorite and acid concentrations in the liquid phase continuously increase to the point of sufficiently high relative chlorous acid levels that disproportionation is accelerated, even at temperatures -OOC.
		The chloride ion in the water, averaging --3.25% as sodium chloride, is an effective catalyst for the rapid degradation of chlorous acid embodied in the frozen solution of acidified sodium chlorite.
		This is seen in the data shown above in Table 1, where sodium chlorite concentrations of 500, 850 and 1200 ppm gave rise to CIO, levels in the chlorine dioxide-containing ice of 56.1, 59.5 and 68.

		In these EAs, the levels of dissolved chlorine dioxide that are typically generated with the acidified sodium chlorite solution (the food additive) will not exceed 1 to 2 mg/liter; i.e., 1 to 2 ppm.
		Based on the 2 ppm generated within the acidified sodium chlorite solution, the EA for FAP 0A4724 estimated the concentration of chlorine dioxide to be 0.02 ppm in the plant effluent or 2.6 ppb in an average POTW influent.
		Furthermore, because oxychlorine species (chlorite, chlorate and chlorine dioxide) readily react with the organic matter and microorganisms in water and soil (sediments) and will undergo ultimate degradation into chloride ion, we anticipate that the expected environmental concentrations for these oxychlorine species will be very small and thus will be of no environmental concern.
