Introduction
Sodium chlorite is a chemical compound with the formula NaClO₂. It is widely used in various industries, including water treatment, disinfection, and even medical applications. This powerful oxidizing agent has gained attention for its effectiveness in eliminating harmful pathogens while being relatively stable under controlled conditions. In this article, we will explore the properties, applications, and safety considerations of sodium chlorite.
Sodium chlorite is a white crystalline powder that dissolves easily in water. It is derived from chlorous acid (HClO₂) and is commonly available in liquid or solid form. Unlike sodium chloride (table salt), sodium chlorite has strong oxidizing properties, making it useful in disinfection and bleaching processes.
Due to its ability to generate chlorine dioxide, sodium chlorite serves as a precursor in many industrial and sanitization applications.
One of the most important uses of sodium chlorite is in water treatment. Municipal water systems and industrial facilities rely on it to produce chlorine dioxide, a potent disinfectant that eliminates bacteria, viruses, and protozoa without forming harmful byproducts like trihalomethanes (THMs).
