Production Process of Sodium Chlorite:
- In general, ClO2, sodium hydroxide, and hydrogen peroxide are the raw materials used in the production of this product. Chlorine dioxide is used as a source of chlorine which is later converted to sodium chlorite.
- Sodium chlorite is obtained indirectly from sodium chlorate. First, sodium chlorate is reduced to chlorine dioxide in a strongly acidic solution using reducing agents such as sodium sulfite, sulfur dioxide, or hydrochloric acid. This substance is then absorbed in an aqueous sodium hydroxide solution, where another reducing agent converts it to sodium chlorite. Hydrogen peroxide can even be used as a reducing agent, producing oxygen gas as a by-product instead of other inorganic salts or substances that can contaminate the product.
Sodium Chlorite Uses:
- Sodium chlorite is used for a variety of applications. as mentioned above sodium chlorite is used for water treatment and also chemical purification.
- It is used as a bleach in the textile industry for a variety of fibers from cotton to synthetic fibers such as nylon.
- In addition, it is used as a bleaching agent in the paper and electronics industries.
- Removal of trihalomethanes from drinking water.
- In addition, sodium chlorite has various industrial uses such as controlling microbial contamination in industrial cooling systems and towers. Because this product is a strong oxidizer, it is commonly used in gas chimney scrubbers.
- Food processing companies use it to wash fruits and vegetables because it is also a strong fungicide. It is also used to wash meat and poultry.
- These compounds are also used for detergents and toothpaste.
- In addition to the industrial applications of this substance, the pharmaceutical grade of this substance is used in the treatment of diseases such as malaria, hepatitis, AIDS, osteoarthritis, colds, etc.
