Production of aqueous chlorine-oxygen solution, used for treating water, e.g. drinking water, or disinfecting swimming pool water, involves adding peroxide compound then aqueous chlorite solution to acidified hydrogen sulfate solution

摘要

Production of chlorite-free, stable aqueous chlorine-oxygen solution (I) comprises: (a) dissolving a hydrogen sulfate compound in water; (b) adding an acid to give a pH of 3-5 in the end product; (c) adding a peroxide compound; and (d) dripping an aqueous chlorite solution into this in an amount of 60-90 mole% with respect to the concentration of peroxide. An Independent claim is also included for the solution (I) produced in this way.
