Determination of Sulfite

Natural water does not contain sulfites. It is usually added to prevent corrosion or in boiler water. Sodium sulfite is added to boiler feed water for conditioning, removing dissolved oxygen and thus preventing pitting.

To prevent corrosion and pitting in closed heaters and economizers, in cooling water, process water, distribution system, etc. to prevent oxygen corrosion. It is also used as catalyzed sulfite in purification.

Since it is not naturally found in water, its presence and amount can be checked in water samples, or it can be tested in waters where it is specifically used.
