Abstract
A method for forming an iodine disinfecting solution that continuously generates free molecular iodine at a controlled average rate of at least 0.2 ppm per hour over a sustained and extended time period. The method involves combining persulfate anions and iodide anions in sufficient quantity in an aqueous medium having a resulting pH of less than about 6.5 so as to create an iodine generating capacity in said aqueous medium of between 1.5 and 6.5 with a generated concentration of at least 5 ppm of free molecular iodine and maintaining this concentration over the course of the extended time period.
