Abstract: Disclosed are a method and a preparation for producing chlorine dioxide for disinfection purposes using a two-component system in an aqueous solution. According to the invention, the two-component system is formed by a chlorite component and a salt component. The chlorite component is composed of an alkaline earth chlorite or alkaline chlorite while the salt component is composed of an alkaline halide or alkaline earth metal halide or sulfate or nitrate and does not have an acid, oxidative, or catalytic effect on the chlorite in an aqueous solution.
