Disinfection Through Oxidation As an oxidizer chlorine dioxide is very selective. It has this ability due to unique one-electron exchange mechanisms. Chlorine dioxide attacks the electron-rich centers of organic molecules. One electron is transferred and chlorine dioxide is reduced to chlorite (ClO2– ). Figure 1: chlorine dioxide is more selective as an oxidizer than chlorine. While
In the very early 1800s, researchers reported independently on a reaction of sulphuric acid with potassium chlorate [Cruickshank 1801; Chenevix 1802]. The yellow gas produced gave indications of the existence of a compound of oxygen and chlorine which Chenevix called hyperoxygenic muriatic acid. For a number of years, researchers thought that the gas was mixture
Chlorine dioxide (ClO2) is a synthetic, green-yellowish gas with a chlorine-like, irritating odor. Chlorine dioxide is a neutral chlorine compound. Chlorine dioxide is very different from elementary chlorine, both in its chemical structure as in its behavior. Chlorine dioxide is a small, volatile and very strong molecule. In diluted, watery solutions chlorine dioxide is a free radical.
