Sodium sulfite is used as a food preservative and is a highly effective reducing and bleaching agent. It is used in the photographic industry to prevent developing solutions from oxidation, as an anticorrosive in water treatment or as an chlorine scavenger in textile industry. Accordingly, BASF provides sodium sulfite in technical, food and photo grades.

Sodium Metabisulfite

In the chemical and pharmaceutical industry, sodium metabisulfite is mainly used as reducing agent. Furthermore, it is ideal for the bleaching of vegetable fibers and textile, for the production of solutions, which are used in the developing of photos and films as well as for the treatment of tanning agents in dyeing of textiles. The chemical properties of sodium metabisulfite make it ideal for water treatment in mining applications.
