Description
Sodium Metabisulfite with the chemical formula (Na2S2O5) is a white compound of hydrogen, sulfur, and oxygen that is inorganic and is known to be one of the strongest chemicals in removing chlorine from water. This inorganic combination of antioxidants and disinfectants is very strong and is used not only in Water treatment and wastewater but also in food production industries such as paper and other industries.
Application
To remove excess chlorine in drinking water and neutralize fertilizer;
To eliminate oxygen in the water and feed water boilers;
In the food industry as a preservative and preventer of food spoilage;
In the plating industry for wastewater treatment containing chromium ions;
In the leather industry to lime removal the skin;
Papermaking (for bleaching wood paste);
This combination is very suitable for use in photo printing darkrooms in photography due to its acidic and preservative properties;
In the cosmetics industry as a preservative;
As a Reducing agent for purification and separation of aldehydes and ketones in the chemical industry;
As a source of SO2 production in gold cyanidation processes.
