Frequently Asked Questions

Sodium chlorite is mainly used to generate chlorine dioxide for treating and disinfecting municipal drinking water or water used in food manufacturing, oil & gas, and other industrial processes. It may also be used for bleaching and stripping textiles, pulp or paper. It is even used for odor control oxidation and etching in electronics.

Sodium chlorite is the sodium salt (and a precursor) of chlorine dioxide. Sodium chlorite is typically sold as a solution and is used to generate chlorine dioxide via chemical reaction. This is typically carried out in a generator on-site of the application. Chlorine dioxide is a gas, which is generally dissolved in water when it is made and the resulting solution applied to the application for various uses such as disinfection, odor control, bleaching, and oxidation.

Yes, ERCOPure sodium chlorite solutions are oxidizing in nature and, as such, they need to stored appropriately and separated from incompatible materials such as acids, reducing agents, and flammable materials. In solution form, the primary hazard is their corrosivity. Great care should be taken to prevent spilled solutions of sodium chlorite from drying to a white salt crystal, which then becomes a fire hazard.

ERCOPure™ sodium chlorite solution is made from electrolysis of high-quality salt brine and then converted to chlorine dioxide with an acid. From there, the pure chlorine dioxide gas is stripped from this solution and converted to sodium chlorite with ultra-pure water, hydrogen peroxide, and caustic soda.
