This specification discloses a biocidal composition and method, by contacting the article with the composition in water. Chlorine dioxide has been suggested as a strong oxidizing agent that is especially useful to kill various microorganisms. The solutions of this invention contain little or no chlorine dioxide or stabilized chlorine dioxide. Instead solutions are disclosed which exhibit biocidal synergism which is developed between the chlorite ion, the chlorate ion and chloride ion when mixed in accordance with the procedures and in the ratios described herein. The instant disclosure provides for mixing various components so as to provide a "redox buffered" equilibrium of intermediate species that are effective as biocidal agents. This is aimed at the formation of such intermediate species instead of the production of chlorine dioxide as taught by the prior art. Thus, the present specification discloses a composition which forms on mixing water, a source of chlorite ions, a source of chloride ions and a source of chlorate ions where the mol ratio of chlorite ions to chlorate ions is in the range from about 2:1 to about 1000:1, the mol ratio of chlorite ions to chloride ions is from about 0.1:1 to about 1000:1 and the mol ratio of chloride ions to chlorate ions is in the range from about 0.1:1 to about 1000:1. The ions would preferably be alkali metal ions, desirably sodium.
